TL;DR:

```shell
$ ./autogen.sh
$ ./configure
$ make
# make install
```

Start by configuring the build running the configure script:

```shell
$ ./configure
```

You can pass options to configure to define build options, to pass it
compiler paths, compiler flags and to define the installation layout. Run
`./configure --help` for more details on how to customize the build.

Once build is completed, build `numactl` with:

```shell
$ make
```

If you would like to increase verbosity by printing the full build command
lines, pass `make` the `V=1` parameter:

```shell
$ make V=1
```

You can build and run the tests included with numactl with the following
command:

```shell
$ make check
```

The results will be saved in `test/*.log` files and a `test-suite.log` will be
generated with the summary of test passes and failures.

Install numactl to the system by running the following command as root:

```shell
# make install
```

You can also install it to a staging directory, in which case it is not
required to be root while running the install steps. Just pass a DESTDIR
variable while running `make install` with the path to the staging
directory.

```shell
$ make install DESTDIR=/path/to/staging/numactl
```

## Using a snapshot from the Git repository

First, the build system files need to be generated using the `./autogen.sh`
script, which calls `autoreconf` with the appropriate options to generate the
configure script and the templates for `Makefile`, `config.h`, etc.

Once those files are generated, follow the normal steps to configure and
build numactl.

In order to create a distribution tarball, use `make dist` from a configured
build tree. Use `make distcheck` to build a distribution tarball and confirm
that rebuilding from that archive works as expected, that building from
out-of-tree works, that test cases pass.

		       Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users.  This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it.  (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.)  You can apply it to
your programs, too.

When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have.  You must make sure that they, too, receive or can get the
source code.  And you must show them these terms so they know their
rights.

We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software.  If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.

Finally, any free program is threatened constantly by software
patents.  We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary.  To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and
modification follow.

GNU GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License.  The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language.  (Hereinafter, translation is included without limitation in
the term "modification".)  Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.

You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

a) You must cause the modified files to carry prominent notices
    stating that you changed the files and the date of any change.

b) You must cause any work that you distribute or publish, that in
    whole or in part contains or is derived from the Program or any
    part thereof, to be licensed as a whole at no charge to all third
    parties under the terms of this License.

c) If the modified program normally reads commands interactively
    when run, you must cause it, when started running for such
    interactive use in the most ordinary way, to print or display an
    announcement including an appropriate copyright notice and a
    notice that there is no warranty (or else, saying that you provide
    a warranty) and that users may redistribute the program under
    these conditions, and telling the user how to view a copy of this
    License.  (Exception: if the Program itself is interactive but
    does not normally print such an announcement, your work based on
    the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.

In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.

3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:

a) Accompany it with the complete corresponding machine-readable
    source code, which must be distributed under the terms of Sections
    1 and 2 above on a medium customarily used for software interchange; or,

b) Accompany it with a written offer, valid for at least three
    years, to give any third party, for a charge no more than your
    cost of physically performing source distribution, a complete
    machine-readable copy of the corresponding source code, to be
    distributed under the terms of Sections 1 and 2 above on a medium
    customarily used for software interchange; or,

c) Accompany it with the information you received as to the offer
    to distribute corresponding source code.  (This alternative is
    allowed only for noncommercial distribution and only if you
    received the program in object code or executable form with such
    an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for
making modifications to it.  For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable.  However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.

If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.

4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License.  Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.

5. You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Program or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.

6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.

7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all.  For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.

8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded.  In such case, this License incorporates
the limitation as if written in the body of this License.

9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

Each version is given a distinguishing version number.  If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation.  If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.

10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission.  For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this.  Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

NO WARRANTY

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

<one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>

This program is free software; you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation; either version 2 of the License, or
    (at your option) any later version.

This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.

You should have received a copy of the GNU General Public License along
    with this program; if not, write to the Free Software Foundation, Inc.,
    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:

Gnomovision version 69, Copyright (C) year name of author
    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License.  Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary.  Here is a sample; alter the names:

Yoyodyne, Inc., hereby disclaims all copyright interest in the program

This General Public License does not permit incorporating your program into
proprietary programs.  If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library.  If this is what you want to do, use the GNU Lesser General

 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

[This is the first released version of the Lesser GPL.  It also counts
 as the successor of the GNU Library Public License, version 2, hence
 the version number 2.1.]

Preamble

The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.

This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it.  You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.

When we speak of free software, we are referring to freedom of use,
not price.  Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.

To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights.  These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.

For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you.  You must make sure that they, too, receive or can get the source
code.  If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it.  And you must show them these terms so they know their rights.

We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.

To protect each distributor, we want to make it very clear that
there is no warranty for the free library.  Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.

Finally, software patents pose a constant threat to the existence of
any free program.  We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder.  Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.

Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License.  This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License.  We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.

When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library.  The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom.  The Lesser General
Public License permits more lax criteria for linking other code with
the library.

We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License.  It also provides other free software developers Less
of an advantage over competing non-free programs.  These disadvantages
are the reason we use the ordinary General Public License for many
libraries.  However, the Lesser license provides advantages in certain
special circumstances.

For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard.  To achieve this, non-free programs must be
allowed to use the library.  A more frequent case is that a free
library does the same job as widely used non-free libraries.  In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.

In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software.  For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.

Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.

The precise terms and conditions for copying, distribution and
modification follow.  Pay close attention to the difference between a
"work based on the library" and a "work that uses the library".  The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.

GNU LESSER GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".

A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.

The "Library", below, refers to any such software library or work
which has been distributed under these terms.  A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language.  (Hereinafter, translation is
included without limitation in the term "modification".)

"Source code" for a work means the preferred form of the work for
making modifications to it.  For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.

Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it).  Whether that is true depends on what the Library does
and what the program that uses the Library does.

1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.

You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.

2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

a) The modified work must itself be a software library.

b) You must cause the files modified to carry prominent notices
    stating that you changed the files and the date of any change.

c) You must cause the whole of the work to be licensed at no
    charge to all third parties under the terms of this License.

d) If a facility in the modified Library refers to a function or a
    table of data to be supplied by an application program that uses
    the facility, other than as an argument passed when the facility
    is invoked, then you must make a good faith effort to ensure that,
    in the event an application does not supply such function or
    table, the facility still operates, and performs whatever part of
    its purpose remains meaningful.

(For example, a function in a library to compute square roots has
    a purpose that is entirely well-defined independent of the
    application.  Therefore, Subsection 2d requires that any
    application-supplied function or table used by this function must
    be optional: if the application does not supply it, the square
    root function must still compute square roots.)

These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.

In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.

3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library.  To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License.  (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.)  Do not make any other change in
these notices.

Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.

This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.

4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.

If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.

5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library".  Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.

However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library".  The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.

When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library.  The
threshold for this to be true is not precisely defined by law.

If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work.  (Executables containing this object code plus portions of the
Library will still fall under Section 6.)

Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.

6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.

You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License.  You must supply a copy of this License.  If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License.  Also, you must do one
of these things:

a) Accompany the work with the complete corresponding
    machine-readable source code for the Library including whatever
    changes were used in the work (which must be distributed under
    Sections 1 and 2 above); and, if the work is an executable linked
    with the Library, with the complete machine-readable "work that
    uses the Library", as object code and/or source code, so that the
    user can modify the Library and then relink to produce a modified
    executable containing the modified Library.  (It is understood
    that the user who changes the contents of definitions files in the
    Library will not necessarily be able to recompile the application
    to use the modified definitions.)

b) Use a suitable shared library mechanism for linking with the
    Library.  A suitable mechanism is one that (1) uses at run time a
    copy of the library already present on the user's computer system,
    rather than copying library functions into the executable, and (2)
    will operate properly with a modified version of the library, if
    the user installs one, as long as the modified version is
    interface-compatible with the version that the work was made with.

c) Accompany the work with a written offer, valid for at
    least three years, to give the same user the materials
    specified in Subsection 6a, above, for a charge no more
    than the cost of performing this distribution.

d) If distribution of the work is made by offering access to copy
    from a designated place, offer equivalent access to copy the above
    specified materials from the same place.

e) Verify that the user has already received a copy of these
    materials or that you have already sent this user a copy.

For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it.  However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.

It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system.  Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.

7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:

a) Accompany the combined library with a copy of the same work
    based on the Library, uncombined with any other library
    facilities.  This must be distributed under the terms of the
    Sections above.

b) Give prominent notice with the combined library of the fact
    that part of it is a work based on the Library, and explaining
    where to find the accompanying uncombined form of the same work.

8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License.  Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License.  However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.

9. You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Library or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.

10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.

11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all.  For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.

If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.

12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded.  In such case, this License incorporates the limitation as if
written in the body of this License.

13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number.  If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation.  If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.

14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission.  For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this.  Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.

NO WARRANTY

15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.

How to Apply These Terms to Your New Libraries

If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change.  You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).

To apply these terms, attach the following notices to the library.  It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.

<one line to give the library's name and a brief idea of what it does.>

This library is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of

Also add information on how to contact you by electronic and paper mail.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary.  Here is a sample; alter the names:

![build test](https://github.com/numactl/numactl/workflows/Makefile%20CI/badge.svg)

Simple NUMA policy support. It consists of a numactl program to run other
programs with a specific NUMA policy and a libnuma shared library ("NUMA API")
to set NUMA policy in applications.

The libnuma binary interface is supposed to stay binary compatible.

Incompatible changes will use new symbol version numbers.

In addition there are various test and utility programs, like `numastat` to
display NUMA allocation statistics and `memhog`.

In `test/` there is a small regression test suite.

Note that `regress` assumes an unloaded machine with memory free on each node.
Otherwise you will get spurious failures in the non-strict policies (preferred,
interleave.)

See the manpages [`numactl.8`](https://linux.die.net/man/8/numactl) and
[`numa.3`](https://linux.die.net/man/3/numa) for details.

`numademo` links with a library derived from the C version of STREAM by John D.
McCalpin and Joe R. Zagar for one sub benchmark. See `stream_lib.c` for the
license. In particular when you publish `numademo` output you might need to pay
attention there or filter out the STREAM results.

It also uses a public domain Mersenne Twister implementation from Michael
Brundage.

\`configure' configures numactl 2.0.16 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/numactl]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

Program names:
  --program-prefix=PREFIX            prepend PREFIX to installed program names
  --program-suffix=SUFFIX            append SUFFIX to installed program names
  --program-transform-name=PROGRAM   run sed PROGRAM on installed program names

System types:
  --build=BUILD     configure for building on BUILD [guessed]
  --host=HOST       cross-compile to build programs to run on HOST [BUILD]

Optional Features:
  --disable-option-checking  ignore unrecognized --enable/--with options
  --disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
  --enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
  --enable-silent-rules   less verbose build output (undo: "make V=1")
  --disable-silent-rules  verbose build output (undo: "make V=0")
  --enable-shared[=PKGS]  build shared libraries [default=yes]
  --enable-static[=PKGS]  build static libraries [default=yes]
  --enable-fast-install[=PKGS]
                          optimize for fast installation [default=yes]
  --enable-dependency-tracking
                          do not reject slow dependency extractors
  --disable-dependency-tracking
                          speeds up one-time build
  --disable-libtool-lock  avoid locking (might break parallel builds)
  --disable-largefile     omit support for large files

Optional Packages:
  --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
  --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
  --with-pic[=PKGS]       try to use only PIC/non-PIC objects [default=use
                          both]
  --with-aix-soname=aix|svr4|both
                          shared library versioning (aka "SONAME") variant to
                          provide on AIX, [default=aix].
  --with-gnu-ld           assume the C compiler uses GNU ld [default=no]
  --with-sysroot[=DIR]    Search for dependent libraries within DIR (or the
                          compiler's sysroot if not specified).

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  LIBS        libraries to pass to the linker, e.g. -l<library>
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  LT_SYS_LIBRARY_PATH
              User-defined run-time library search path.

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

Report bugs to the package provider.

Oops!

Your 'rm' program seems unable to run without file operands specified
on the command line, even when the '-f' option is present.  This is contrary
to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard: <http://austingroupbugs.net/view.php?id=542>

Please tell bug-automake@gnu.org about your system, including the value
of your $PATH and any error possibly output before this message.  This
can help us improve future automake versions.

Aborting the configuration process, to ensure you take notice of the issue.

You can download and install GNU coreutils to get an 'rm' implementation
that behaves properly: <https://www.gnu.org/software/coreutils/>.

If you want to complete the configuration process using your problematic
'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
to "yes", and re-run configure.

# ===========================================================================
#
# SYNOPSIS
#
#   AX_AM_OVERRIDE_VAR([varname1 varname ... ])
#   AX_AM_OVERRIDE_FINALIZE
#
# DESCRIPTION
#
#   This autoconf macro generalizes the approach given in
#   <http://lists.gnu.org/archive/html/automake/2005-09/msg00108.html> which
#   moves user specified values for variable 'varname' given at configure
#   time into the corresponding AM_${varname} variable and clears out
#   'varname', allowing further manipulation by the configure script so that
#   target specific variables can be given specialized versions.  'varname
#   may still be specified on the make command line and will be appended as
#   usual.
#
#   As an example usage, consider a project which might benefit from
#   different compiler flags for different components. Typically this is
#   done via target specific flags, e.g.
#
#    libgtest_la_CXXFLAGS    =                        \
#                     -I $(top_srcdir)/tests          \
#                     -I $(top_builddir)/tests        \
#                     $(GTEST_CXXFLAGS)
#
#   automake will automatically append $(CXXFLAGS) -- provided by the user
#   -- to the build rule for libgtest_la.  That might be problematic, as
#   CXXFLAGS may contain compiler options which are inappropriate for
#   libgtest_la.
#
#   The approach laid out in the referenced mailing list message is to
#   supply a base value for a variable during _configure_ time, during which
#   it is possible to amend it for specific targets. The user may
#   subsequently specify a value for the variable during _build_ time, which
#   make will apply (via the standard automake rules) to all appropriate
#   targets.
#
#   For example,
#
#    AX_AM_OVERRIDE_VAR([CXXFLAGS])
#
#   will store the value of CXXFLAGS specified at configure time into the
#   AM_CXXFLAGS variable, AC_SUBST it, and clear CXXFLAGS. configure may
#   then create a target specific set of flags based upon AM_CXXFLAGS, e.g.
#
#    # googletest uses variadic macros, which g++ -pedantic-errors
#    # is very unhappy about
#    AC_SUBST([GTEST_CXXFLAGS],
#       [`AS_ECHO_N(["$AM_CXXFLAGS"]) \
#             | sed s/-pedantic-errors/-pedantic/`
#        ]
#     )
#
#   which would be used in a Makefile.am as above.  Since CXXFLAGS is
#   cleared, the configure time value will not affect the build for
#   libgtest_la.
#
#   Prior to _any other command_ which may set ${varname}, call
#
#    AX_AM_OVERRIDE_VAR([varname])
#
#   This will preserve the value (if any) passed to configure in
#   AM_${varname} and AC_SUBST([AM_${varname}).  You may pass a space
#   separated list of variable names, or may call AX_AM_OVERRIDE_VAR
#   multiple times for the same effect.
#
#   If any subsequent configure commands set ${varname} and you wish to
#   capture the resultant value into AM_${varname} in the case where
#   ${varname} was _not_ provided at configure time,  call
#
#    AX_AM_OVERRIDE_FINALIZE
#
#   after _all_ commands which might affect any of the variables specified
#   in calls to AX_AM_OVERRIDE_VAR.  This need be done only once, but
#   repeated calls will not cause harm.
#
#   There is a bit of trickery required to allow further manipulation of the
#   AM_${varname} in a Makefile.am file.  If AM_CFLAGS is used as is in a
#   Makefile.am, e.g.
#
#    libfoo_la_CFLAGS = $(AM_CFLAGS)
#
#   then automake will emit code in Makefile.in which sets AM_CFLAGS from
#   the configure'd value.
#
#   If however, AM_CFLAGS is manipulated (i.e. appended to), you will have
#   to explicitly arrange for the configure'd value to be substituted:
#
#    AM_CFLAGS = @AM_CFLAGS@
#    AM_CFLAGS += -lfoo
#
#   or else automake will complain about using += before =.

#
# SYNOPSIS
#
#   AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
#
# DESCRIPTION
#
#   Check whether the given FLAG works with the current language's compiler
#   or gives an error.  (Warnings, however, are ignored)
#
#   ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
#   success/failure.
#
#   If EXTRA-FLAGS is defined, it is added to the current language's default
#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
#   force the compiler to issue an error when a bad flag is given.
#
#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
#
#   NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
#   macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

#
#   Provides a test for the compiler support of thread local storage (TLS)

.SH NAME
memhog \- Allocates memory with policy for testing
.SH SYNOPSIS
.B memhog 
[
.B \-r<NUM>
] [
.B size kmg
] [
.B policy nodeset
] [
.B \-f<filename>
]
.SH DESCRIPTION
.B memhog 
mmaps a memory region for a given size and sets the numa policy (if specified). 
It then updates the memory region for the given number of iterations using memset.
.TS
tab(|);
l l.
-r<num>|Repeat memset NUM times
-f<file>|Open file for mmap backing
-H|Disable transparent hugepages
-size|Allocation size in bytes, may have case-insensitive order 
|suffix (G=gigabyte, M=megabyte, K=kilobyte)
.TE

Supported numa-policies:
.TP
.B interleave 
Memory will be allocated using round robin on nodes. When
memory cannot be allocated on the current interleave, target fall back 
to other nodes.  Multiple nodes may be specified.
.TP
.B membind 
Only  allocate  memory  from  nodes. Allocation will fail 
when there is not enough memory available on these nodes. Multiple 
nodes  may be specified.
.TP
.B preferred 
Preferably allocate memory on node, but if memory cannot be
allocated  there  fall  back  to other nodes.  This option takes only a 
single node number.
.TP
.B default 
Memory will be allocated on the local node (the node the 
thread is running on)

.SH EXAMPLES
.TP
# Allocate a 1G region, mmap backed by memhog.mmap file, membind to node 0, repeat test 6 times
memhog -r6 1G --membind 0 -fmemhog.mmap
.TP
# Allocate a 1G region, interleave across nodes 0,1,2,3, repeat test 4 times
memhog -r4 1G --interleave 0-3
.TP
# Allocate a 1G region, (implicit) default policy, repeat test 8 times
memhog -r8 1G

.SH NAME
migratepages \- Migrate the physical location a processes pages
.SH SYNOPSIS
.B migratepages
pid from-nodes to-nodes
.SH DESCRIPTION
.B migratepages
moves the physical location of a processes pages without any changes of the
virtual address space of the process. Moving the pages allows one to change
the distances of a process to its memory. Performance may be optimized by moving
a processes pages to the node where it is executing.

If multiple nodes are specified for from-nodes or to-nodes then
an attempt is made to preserve the relative location of
each page in each nodeset.

For example if we move from nodes 2-5 to 7,9,12-13 then the preferred mode of
operation is to move pages from 2->7, 3->9, 4->12 and 5->13. However, this
is only posssible if enough memory is available.
.TP
Valid node specifiers

all:All nodes
number:Node number

number1-number2:Nodes from number1 to number2
! nodes:Invert selection of the following specification.
.TE
.SH NOTES
Requires a NUMA policy aware kernel with support for page migration
(linux 2.6.16 and later).

migratepages will only move pages that are not shared with other
processes if called by a user without administrative priviledges (but
with the right to modify the process).

migratepages will move all pages if invoked from root (or a user with
administrative priviledges).

.SH NAME
move_pages \- Move individual pages of a process to another node
.SH SYNOPSIS
.B #include <numaif.h>
.sp
.BI "long move_pages(int " pid ", unsigned long count, void ** " pages ", const int * " nodes ", int * " status ", int " flags );
.SH DESCRIPTION
.BR move_pages ()
moves
.I count
pages to the
.I nodes.
The result of the move is reflected in
.I status.
The
.I flags
indicate constraints on the pages to be moved.

.I pid
is the process id in which pages are to be moved. Sufficient rights
must exist to move pages of another process. This means the moving
process either has root priviledges, has SYS_NICE administrative rights or
the same owner. If pid is 0 then we move pages of the current process.

.I count
is the number of pages to move. It defines the size of the three
arrays
.I pages,
.I nodes
and
.I status.

.I pages
is an array of pointers to the pages that should be moved. These are pointers
that should be aligned to page boundaries. Addresses are specified as seen by
the process specified by
.I pid.

.I nodes
is either an array of integers that specify the desired location for each
page or it is NULL. Each integer is a node number. If NULL is specified then
move_pages will not move any pages but return the node of each page in
the
.I status
array. Having the status of each page may be necessary to determine
pages that need to be moved.

.I status
is an array of integers that return the status of each page. The array
only contains valid values if
.I move_pages
did not return an error code.

.I flags
specify what types of pages to move.
.B MPOL_MF_MOVE
means that only pages that are in exclusive use by the process
are to be moved.
.B MPOL_MF_MOVE_ALL
means that pages shared between multiple processes can also be moved.
The process must have root priviledges or SYS_NICE priviledges.

.SH Page states in the status array

.TP
.B 0..MAX_NUMNODES
Indicates that the location of the page is on this node.
.TP
.B -ENOENT
The page is not present.
.TP
.B -EACCES
The page is mapped by multiple processes and can only be moved
if
.I MPOL_MF_MOVE_ALL
is specified.
.TP
.B -EBUSY
The page is currently busy and cannot be moved. Try again later.
This occurs if a page is undergoing I/O or another kernel subsystem
is holding a reference to the page.
.TP
.B -EFAULT
This is a zero page or the memory area is not mapped by the process.
.TP
.B -ENOMEM
Unable to allocate memory on target node.
.TP
.B -EIO
Unable to write back a page. The page has to be written back
in order to move ti since the page is dirty and the filesystem
has not provide a migration function that would allow the move
of dirty pages.
.TP
.B -EINVAL
A dirty page cannot be moved. The filesystem does not
provide a migration function and has no ability to write back pages.

.SH "RETURN VALUE"
On success
.B move_pages
returns zero.
.SH ERRORS
.TP
.B -ENOENT
No pages were found that require moving. All pages are either already
on the target node, not present, had an invalid address or could not be
moved because they were mapped by multiple processes.
.TP
.B -EINVAL
Flags other than
.I MPOL_MF_MOVE
and
.I MPOL_MF_MOVE_ALL
was specified or an attempt was made to migrate pages of a kernel thread.
.TP
.B -EPERM
.I MPOL_MF_MOVE_ALL
specified without sufficient privileges or an attempt to move a process
belonging to another user.
.TP
.B -EACCESS
On of the target nodes is not allowed by the current cpuset.
.TP
.B -ENODEV
On of the target nodes is not online.
.TP
.B -ESRCH
Process does not exist.
.TP
.B -E2BIG
Too many pages to move.
.TP
.B -EFAULT
Parameter array could not be accessed.

.SH DESCRIPTION
The
.I libnuma
library offers a simple programming interface to the
NUMA (Non Uniform Memory Access)
policy supported by the
Linux kernel. On a NUMA architecture some
memory areas have different latency or bandwidth than others.

Available policies are
page interleaving (i.e., allocate in a round-robin fashion from all,
or a subset, of the nodes on the system),
preferred node allocation (i.e., preferably allocate on a particular node),
local allocation (i.e., allocate on the node on which
the task is currently executing),
or allocation only on specific nodes (i.e., allocate on
some subset of the available nodes).
It is also possible to bind tasks to specific nodes.

Numa memory allocation policy may be specified as a per-task attribute,
that is inherited by children tasks and processes, or as an attribute
of a range of process virtual address space.
Numa memory policies specified for a range of virtual address space are
shared by all tasks in the process.
Furthermore, memory policies specified for a range of a shared memory
attached using
.I shmat(2)
or
.I mmap(2)
from shmfs/hugetlbfs are shared by all processes that attach to that region.
Memory policies for shared disk backed file mappings are currently ignored.

The default memory allocation policy for tasks and all memory range
is local allocation.
This assumes that no ancestor has installed a non-default policy.

For setting a specific policy globally for all memory allocations
in a process and its children it is easiest
to start it with the
.BR numactl (8)
utility. For more finegrained policy inside an application this library
can be used.

All numa memory allocation policy only takes effect when a page is actually
faulted into the address space of a process by accessing it. The
.B numa_alloc_*
functions take care of this automatically.

A
.I node
is defined as an area where all memory has the same speed as seen from
a particular CPU.
A node can contain multiple CPUs.
Caches are ignored for this definition.

Most functions in this library are only concerned about numa nodes and
their memory.
The exceptions to this are:
.IR numa_node_to_cpus (),
.IR numa_node_to_cpu_update (),
.IR numa_node_of_cpu (),
.IR numa_bind (),
.IR numa_run_on_node (),
.IR numa_run_on_node_mask (),
.IR numa_run_on_node_mask_all (),
and
.IR numa_get_run_node_mask ().
These functions deal with the CPUs associated with numa nodes.
See the descriptions below for more information.

Some of these functions accept or return a pointer to struct bitmask.
A struct bitmask controls a bit map of arbitrary length containing a bit
representation of nodes.  The predefined variable
.I numa_all_nodes_ptr
points to a bit mask that has all available nodes set;
.I numa_no_nodes_ptr
points to the empty set.

Before any other calls in this library can be used
.BR numa_available ()
must be called. If it returns \-1, all other functions in this
library are undefined.

.BR numa_max_possible_node()
returns the number of the highest possible node in a system.
In other words, the size of a kernel type nodemask_t (in bits) minus 1.
This number can be gotten by calling
.BR numa_num_possible_nodes()
and subtracting 1.

.BR numa_num_possible_nodes()
returns the size of kernel's node mask (kernel type nodemask_t).
In other words, large enough to represent the maximum number of nodes that
the kernel can handle. This will match the kernel's MAX_NUMNODES value.
This count is derived from /proc/self/status, field Mems_allowed.

.BR numa_max_node ()
returns the highest node number available on the current system.
(See the node numbers in /sys/devices/system/node/ ).  Also see
.BR numa_num_configured_nodes().

.BR numa_num_configured_nodes()
returns the number of memory nodes in the system. This count
includes any nodes that are currently disabled. This count is derived from
the node numbers in /sys/devices/system/node. (Depends on the kernel being
configured with /sys (CONFIG_SYSFS)).

.BR numa_get_mems_allowed()
returns the mask of nodes from which the process is allowed to allocate
memory in it's current cpuset context.
Any nodes that are not included in the returned bitmask will be ignored
in any of the following libnuma memory policy calls.

.BR numa_num_configured_cpus()
returns the number of cpus in the system.  This count includes
any cpus that are currently disabled. This count is derived from the cpu
numbers in /sys/devices/system/cpu. If the kernel is configured without
/sys (CONFIG_SYSFS=n) then it falls back to using the number of online cpus.

.BR numa_all_nodes_ptr
points to a bitmask that is allocated by the library with bits
representing all nodes on which the calling task may allocate memory.
This set may be up to all nodes on the system, or up to the nodes in
the current cpuset.
The bitmask is allocated by a call to
.BR numa_allocate_nodemask()
using size
.BR numa_max_possible_node().
The set of nodes to record is derived from /proc/self/status, field
"Mems_allowed".  The user should not alter this bitmask.

.BR numa_no_nodes_ptr
points to a bitmask that is allocated by the library and left all
zeroes.  The bitmask is allocated by a call to
.BR numa_allocate_nodemask()
using size
.BR numa_max_possible_node().
The user should not alter this bitmask.

.BR numa_all_cpus_ptr
points to a bitmask that is allocated by the library with bits
representing all cpus on which the calling task may execute.
This set may be up to all cpus on the system, or up to the cpus in
the current cpuset.
The bitmask is allocated by a call to
.BR numa_allocate_cpumask()
using size
.BR numa_num_possible_cpus().
The set of cpus to record is derived from /proc/self/status, field
"Cpus_allowed".  The user should not alter this bitmask.

.BR numa_num_task_cpus()
returns the number of cpus that the calling task is allowed
to use.  This count is derived from the map /proc/self/status, field
"Cpus_allowed". Also see the bitmask
.BR numa_all_cpus_ptr.

.BR numa_num_task_nodes()
returns the number of nodes on which the calling task is
allowed to allocate memory.  This count is derived from the map
/proc/self/status, field "Mems_allowed".
Also see the bitmask
.BR numa_all_nodes_ptr.

.BR numa_parse_bitmap()
parses
.I line
, which is a character string such as found in
/sys/devices/system/node/nodeN/cpumap into a bitmask structure.
The string contains the hexadecimal representation of a bit map.
The bitmask may be allocated with
.BR numa_allocate_cpumask().
Returns  0 on success.  Returns -1 on failure.
This function is probably of little use to a user application, but
it is used by
.I libnuma
internally.

.BR numa_parse_nodestring()
parses a character string list of nodes into a bit mask.
The bit mask is allocated by
.BR numa_allocate_nodemask().
The string is a comma-separated list of node numbers or node ranges.
A leading ! can be used to indicate "not" this list (in other words, all
nodes except this list), and a leading + can be used to indicate that the
node numbers in the list are relative to the task's cpuset.  The string can
be "all" to specify all (
.BR numa_num_task_nodes()
) nodes.  Node numbers are limited by the number in the system.  See
.BR numa_max_node()
and
.BR numa_num_configured_nodes().
.br
Examples:  1-5,7,10   !4-5   +0-3
.br
If the string is of 0 length, bitmask
.BR numa_no_nodes_ptr
is returned.  Returns 0 if the string is invalid.

.BR numa_parse_nodestring_all()
is similar to
.BR numa_parse_nodestring
, but can parse all possible nodes, not only current nodeset.

.BR numa_parse_cpustring()
parses a character string list of cpus into a bit mask.
The bit mask is allocated by
.BR numa_allocate_cpumask().
The string is a comma-separated list of cpu numbers or cpu ranges.
A leading ! can be used to indicate "not" this list (in other words, all
cpus except this list), and a leading + can be used to indicate that the cpu
numbers in the list are relative to the task's cpuset.  The string can be
"all" to specify all (
.BR numa_num_task_cpus()
) cpus.
Cpu numbers are limited by the number in the system.  See
.BR numa_num_task_cpus()
and
.BR numa_num_configured_cpus().
.br
Examples:  1-5,7,10   !4-5   +0-3
.br
Returns 0 if the string is invalid.

.BR numa_parse_cpustring_all()
is similar to
.BR numa_parse_cpustring
, but can parse all possible cpus, not only current cpuset.

.BR numa_node_size ()
returns the memory size of a node. If the argument
.I freep
is not NULL, it used to return the amount of free memory on the node.
On error it returns \-1.

.BR numa_node_size64 ()
works the same as
.BR numa_node_size ().
This is useful on 32-bit architectures with large nodes.

.BR numa_preferred ()
returns the preferred node of the current task.
This is the node on which the kernel preferably
allocates memory, unless some other policy overrides this.
.\" TODO:   results are misleading for MPOL_PREFERRED and may
.\" be incorrect for MPOL_BIND when Mel Gorman's twozonelist
.\" patches go in.  In the latter case, we'd need to know the
.\" order of the current node's zonelist to return the correct
.\" node.  Need to tighten this up with the syscall results.

.BR numa_has_preferred_many ()
Returns > 0 if the system supports multiple preferred nodes.

.BR numa_preferred_many ()
Returns the current set of preferred nodes. This implies the empty set when the
policy isn't one used for preference
.I (PREFERRED, PREFERRED_MANY, BIND).
The caller is responsible for freeing the mask with
.BR numa_bitmask_free ().

.BR numa_set_preferred ()
sets the preferred node for the current task to
.IR node .
The system will attempt to allocate memory from the preferred node,
but will fall back to other nodes if no memory is available on the
the preferred node.
Passing a
.I node
of \-1 argument specifies local allocation and is equivalent to
calling
.BR numa_set_localalloc ().

.BR numa_set_preferred_many ()
sets the preferred set of nodes for the current task to
.IR nodemask .
This is similar to
.BR numa_set_preferred ()
with the exception that it utilizes a different kernel interface to specify
multiple preferred nodes.
The caller is responsible for freeing the mask with
.BR numa_bitmask_free ().

.BR numa_get_interleave_mask ()
returns the current interleave mask if the task's memory allocation policy
is page interleaved.
Otherwise, this function returns an empty mask.

.BR numa_set_interleave_mask ()
sets the memory interleave mask for the current task to
.IR nodemask .
All new memory allocations
are page interleaved over all nodes in the interleave mask. Interleaving
can be turned off again by passing an empty mask
.RI ( numa_no_nodes ).
The page interleaving only occurs on the actual page fault that puts a new
page into the current address space. It is also only a hint: the kernel
will fall back to other nodes if no memory is available on the interleave
target.
.\" NOTE:  the following is not really the case.  this function sets the
.\" task policy for all future allocations, including stack,  bss, ...
.\" The functions specified in this sentence actually allocate a new memory
.\" range [via mmap()].  This is quite a different thing.  Suggest we drop
.\" this.
.\" This is a low level
.\" function, it may be more convenient to use the higher level functions like
.\" .BR numa_alloc_interleaved ()
.\" or
.\" .BR numa_alloc_interleaved_subset ().

.BR numa_interleave_memory ()
interleaves
.I size
bytes of memory page by page from
.I start
on nodes specified in
.IR nodemask .
The
.I size
argument will be rounded up to a multiple of the system page size.
If
.I nodemask
contains nodes that are externally denied to this process,
this call will fail.
This is a lower level function to interleave allocated but not yet faulted in
memory. Not yet faulted in means the memory is allocated using
.BR mmap (2)
or
.BR shmat (2),
but has not been accessed by the current process yet. The memory is page
interleaved to all nodes specified in
.IR nodemask .
Normally
.BR numa_alloc_interleaved ()
should be used for private memory instead, but this function is useful to
handle shared memory areas. To be useful the memory area should be
several megabytes at least (or tens of megabytes of hugetlbfs mappings)
If the
.BR numa_set_strict ()
flag is true then the operation will cause a numa_error if there were already
pages in the mapping that do not follow the policy.

.BR numa_bind ()
binds the current task and its children to the nodes
specified in
.IR nodemask .
They will only run on the CPUs of the specified nodes and only be able to allocate
memory from them.
This function is equivalent to calling
.\" FIXME checkme
.\" This is the case.  --lts
.I numa_run_on_node_mask(nodemask)
followed by
.IR numa_set_membind(nodemask) .
If tasks should be bound to individual CPUs inside nodes
consider using
.I numa_node_to_cpus
and the
.I sched_setaffinity(2)
syscall.

.BR numa_set_localalloc ()
sets the memory allocation policy for the calling task to
local allocation.
In this mode, the preferred node for memory allocation is
effectively the node where the task is executing at the
time of a page allocation.

.BR numa_set_membind ()
sets the memory allocation mask.
The task will only allocate memory from the nodes set in
.IR nodemask .
Passing an empty
.I nodemask
or a
.I nodemask
that contains nodes other than those in the mask returned by
.IR numa_get_mems_allowed ()
will result in an error.

.BR numa_set_membind_balancing ()
sets the memory allocation mask and enable the Linux kernel NUMA
balancing for the task if the feature is supported by the kernel.
The task will only allocate memory from the nodes set in
.IR nodemask .
Passing an empty
.I nodemask
or a
.I nodemask
that contains nodes other than those in the mask returned by
.IR numa_get_mems_allowed ()
will result in an error.

.BR numa_get_membind ()
returns the mask of nodes from which memory can currently be allocated.
If the returned mask is equal to
.IR numa_all_nodes ,
then memory allocation is allowed from all nodes.

.BR numa_alloc_onnode ()
allocates memory on a specific node.
The
.I size
argument will be rounded up to a multiple of the system page size.
if the specified
.I node
is externally denied to this process, this call will fail.
This function is relatively slow compared to the
.IR malloc (3)
family of functions.
The memory must be freed
with
.BR numa_free ().
On errors NULL is returned.

.BR numa_alloc_local ()
allocates
.I size
bytes of memory on the local node.
The
.I size
argument will be rounded up to a multiple of the system page size.
This function is relatively slow compared to the
.IR malloc (3)
family of functions.
The memory must be freed
with
.BR numa_free ().
On errors NULL is returned.

.BR numa_alloc_interleaved ()
allocates
.I size
bytes of memory page interleaved on all nodes. This function is relatively slow
and should only be used for large areas consisting of multiple pages. The
interleaving works at page level and will only show an effect when the
area is large.
The allocated memory must be freed with
.BR numa_free ().
On error, NULL is returned.

.BR numa_alloc_interleaved_subset ()
attempts to allocate
.I size
bytes of memory page interleaved on all nodes.
The
.I size
argument will be rounded up to a multiple of the system page size.
The nodes on which a process is allowed to allocate memory may
be constrained externally.
If this is the case, this function may fail.
This function is relatively slow compared to the
.IR malloc (3)
family of functions and should only be used for large areas consisting
of multiple pages.
The interleaving works at page level and will only show an effect when the
area is large.
The allocated memory must be freed with
.BR numa_free ().
On error, NULL is returned.

.BR numa_alloc ()
allocates
.I size
bytes of memory with the current NUMA policy.
The
.I size
argument will be rounded up to a multiple of the system page size.
This function is relatively slow compared to the
.IR malloc (3)
family of functions.
The memory must be freed
with
.BR numa_free ().
On errors NULL is returned.

.BR numa_realloc ()
changes the size of the memory area pointed to by
.I old_addr
from
.I old_size
to
.I new_size.
The memory area pointed to by
.I old_addr
must have been allocated with one of the
.BR numa_alloc*
functions.
The
.I new_size
will be rounded up to a multiple of the system page size. The contents of the
memory area will be unchanged to the minimum of the old and new sizes; newly
allocated memory will be uninitialized. The memory policy (and node bindings)
associated with the original memory area will be preserved in the resized
area. For example, if the initial area was allocated with a call to
.BR numa_alloc_onnode(),
then the new pages (if the area is enlarged) will be allocated on the same node.
However, if no memory policy was set for the original area, then
.BR numa_realloc ()
cannot guarantee that the new pages will be allocated on the same node. On
success, the address of the resized area is returned (which might be different
from that of the initial area), otherwise NULL is returned and
.I errno
is set to indicate the error. The pointer returned by
.BR numa_realloc ()
is suitable for passing to
.BR numa_free ().

.BR numa_free ()
frees
.I size
bytes of memory starting at
.IR start ,
allocated by the
.B numa_alloc_*
functions above.
The
.I size
argument will be rounded up to a multiple of the system page size.

.BR numa_run_on_node ()
runs the current task and its children
on a specific node. They will not migrate to CPUs of
other nodes until the node affinity is reset with a new call to
.BR numa_run_on_node_mask ().
Passing \-1
permits the kernel to schedule on all nodes again.
On success, 0 is returned; on error \-1 is returned, and
.I errno
is set to indicate the error.

.BR numa_run_on_node_mask ()
runs the current task and its children only on nodes specified in
.IR nodemask .
They will not migrate to CPUs of
other nodes until the node affinity is reset with a new call to
.BR numa_run_on_node_mask ()
or
.BR numa_run_on_node ().
Passing
.I numa_all_nodes
permits the kernel to schedule on all nodes again.
On success, 0 is returned; on error \-1 is returned, and
.I errno
is set to indicate the error.

.BR numa_run_on_node_mask_all ()
runs the current task and its children only on nodes specified in
.IR nodemask
like
.I numa_run_on_node_mask
but without any cpuset awareness.

.BR numa_get_run_node_mask ()
returns a mask of CPUs on which the current task is allowed to run.

.BR numa_tonode_memory ()
put memory on a specific node. The constraints described for
.BR numa_interleave_memory ()
apply here too.

.BR numa_tonodemask_memory ()
put memory on a specific set of nodes. The constraints described for
.BR numa_interleave_memory ()
apply here too.

.BR numa_setlocal_memory ()
locates memory on the current node. The constraints described for
.BR numa_interleave_memory ()
apply here too.

.BR numa_police_memory ()
locates memory with the current NUMA policy. The constraints described for
.BR numa_interleave_memory ()
apply here too. The function will read-modify-write parts of the memory, and it's the callers
responsibility to avoid data races with parallel threads.

.BR numa_distance ()
reports the distance in the machine topology between two nodes.
The factors are a multiple of 10. It returns 0 when the distance
cannot be determined. A node has distance 10 to itself.
Reporting the distance requires a Linux
kernel version of
.I 2.6.10
or newer.

.BR numa_set_bind_policy ()
specifies whether calls that bind memory to a specific node should
use the preferred policy or a strict policy.
The preferred policy allows the kernel
to allocate memory on other nodes when there isn't enough free
on the target node. strict will fail the allocation in that case.
Setting the argument to specifies strict, 0 preferred.
Note that specifying more than one node non strict may only use
the first node in some kernel versions.

.BR numa_set_strict ()
sets a flag that says whether the functions allocating on specific
nodes should use use a strict policy. Strict means the allocation
will fail if the memory cannot be allocated on the target node.
Default operation is to fall back to other nodes.
This doesn't apply to interleave and default.

.BR numa_get_interleave_node()
is used by
.I libnuma
internally. It is probably not useful for user applications.
It uses the MPOL_F_NODE flag of the get_mempolicy system call, which is
not intended for application use (its operation may change or be removed
altogether in future kernel versions). See get_mempolicy(2).

.BR numa_pagesize()
returns the number of bytes in page. This function is simply a fast
alternative to repeated calls to the getpagesize system call.
See getpagesize(2).

.BR numa_sched_getaffinity()
retrieves a bitmask of the cpus on which a task may run.  The task is
specified by
.I pid.
Returns the return value of the sched_getaffinity
system call.  See sched_getaffinity(2).
The bitmask must be at least the size of the kernel's cpu mask structure. Use
.BR numa_allocate_cpumask()
to allocate it.
Test the bits in the mask by calling
.BR numa_bitmask_isbitset().

.BR numa_sched_setaffinity()
sets a task's allowed cpu's to those cpu's specified in
.I mask.
The task is specified by
.I pid.
Returns the return value of the sched_setaffinity system call.
See sched_setaffinity(2).  You may allocate the bitmask with
.BR numa_allocate_cpumask().
Or the bitmask may be smaller than the kernel's cpu mask structure. For
example, call
.BR numa_bitmask_alloc()
using a maximum number of cpus from
.BR numa_num_configured_cpus().
Set the bits in the mask by calling
.BR numa_bitmask_setbit().

.BR numa_node_to_cpus ()
converts a node number to a bitmask of CPUs. The user must pass a bitmask
structure with a mask buffer long enough to represent all possible cpu's.
Use numa_allocate_cpumask() to create it.  If the bitmask is not long enough
.I errno
will be set to
.I ERANGE
and \-1 returned. On success 0 is returned.

.BR numa_node_to_cpu_update ()
Mark cpus bitmask of all nodes stale, then get the latest bitmask by calling
.BR numa_node_to_cpus ()
This allows to update the libnuma state after a CPU hotplug event. The application
is in charge of detecting CPU hotplug events.

.BR numa_node_of_cpu ()
returns the node that a cpu belongs to. If the user supplies an invalid cpu
.I errno
will be set to
.I EINVAL
and \-1 will be returned.

.BR numa_allocate_cpumask
() returns a bitmask of a size equal to the kernel's cpu
mask (kernel type cpumask_t).  In other words, large enough to represent
NR_CPUS cpus.  This number of cpus can be gotten by calling
.BR numa_num_possible_cpus().
The bitmask is zero-filled.

.BR numa_free_cpumask
frees a cpumask previously allocate by
.I numa_allocate_cpumask.

.BR numa_allocate_nodemask()
returns a bitmask of a size equal to the kernel's node
mask (kernel type nodemask_t).  In other words, large enough to represent
MAX_NUMNODES nodes.  This number of nodes can be gotten by calling
.BR numa_num_possible_nodes().
The bitmask is zero-filled.

.BR numa_free_nodemask()
frees a nodemask previous allocated by
.I numa_allocate_nodemask().

.BR numa_bitmask_alloc()
allocates a bitmask structure and its associated bit mask.
The memory allocated for the bit mask contains enough words (type unsigned
long) to contain
.I n
bits.  The bit mask is zero-filled.  The bitmask
structure points to the bit mask and contains the
.I n
value.

.BR numa_bitmask_clearall()
sets all bits in the bit mask to 0.  The bitmask structure
points to the bit mask and contains its size (
.I bmp
->size).  The value of
.I bmp
is always returned.  Note that
.BR numa_bitmask_alloc()
creates a zero-filled bit mask.

.BR numa_bitmask_clearbit()
sets a specified bit in a bit mask to 0.  Nothing is done if
the
.I n
value is greater than the size of the bitmask (and no error is
returned). The value of
.I bmp
is always returned.

.BR numa_bitmask_equal()
returns 1 if two bitmasks are equal.  It returns 0 if they
are not equal.  If the bitmask structures control bit masks of different
sizes, the "missing" trailing bits of the smaller bit mask are considered
to be 0.

.BR numa_bitmask_free()
deallocates the memory of both the bitmask structure pointed
to by
.I bmp
and the bit mask.  It is an error to attempt to free this bitmask twice.

.BR numa_bitmask_isbitset()
returns the value of a specified bit in a bit mask.
If the
.I n
value is greater than the size of the bit map, 0 is returned.

.BR numa_bitmask_nbytes()
returns the size (in bytes) of the bit mask controlled by
.I bmp.
The bit masks are always full words (type unsigned long), and the returned
size is the actual size of all those words.

.BR numa_bitmask_setall()
sets all bits in the bit mask to 1.  The bitmask structure
points to the bit mask and contains its size (
.I bmp
->size).
The value of
.I bmp
is always returned.

.BR numa_bitmask_setbit()
sets a specified bit in a bit mask to 1.  Nothing is done if
.I n
is greater than the size of the bitmask (and no error is
returned). The value of
.I bmp
is always returned.

.BR copy_bitmask_to_nodemask()
copies the body (the bit map itself) of the bitmask structure pointed
to by
.I bmp
to the nodemask_t structure pointed to by the
.I nodemask
pointer. If the two areas differ in size, the copy is truncated to the size
of the receiving field or zero-filled.

.BR copy_nodemask_to_bitmask()
copies the nodemask_t structure pointed to by the
.I nodemask
pointer to the body (the bit map itself) of the bitmask structure pointed
to by the
.I bmp
pointer. If the two areas differ in size, the copy is truncated to the size
of the receiving field or zero-filled.

.BR copy_bitmask_to_bitmask()
copies the body (the bit map itself) of the bitmask structure pointed
to by the
.I bmpfrom
pointer to the body of the bitmask structure pointed to by the
.I bmpto
pointer. If the two areas differ in size, the copy is truncated to the size
of the receiving field or zero-filled.

.BR numa_bitmask_weight()
returns a count of the bits that are set in the body of the bitmask pointed
to by the
.I bmp
argument.

.br
.BR numa_move_pages()
moves a list of pages in the address space of the currently
executing or current process.
It simply uses the move_pages system call.
.br
.I pid
- ID of task.  If not valid, use the current task.
.br
.I count
- Number of pages.
.br
.I pages
- List of pages to move.
.br
.I nodes
- List of nodes to which pages can be moved.
.br
.I status
- Field to which status is to be returned.
.br
.I flags
- MPOL_MF_MOVE or MPOL_MF_MOVE_ALL
.br
See move_pages(2).

.BR numa_migrate_pages()
simply uses the migrate_pages system call to cause the pages of the calling
task, or a specified task, to be migated from one set of nodes to another.
See migrate_pages(2).
The bit masks representing the nodes should be allocated with
.BR numa_allocate_nodemask()
, or with
.BR numa_bitmask_alloc()
using an
.I n
value returned from
.BR numa_num_possible_nodes().
A task's current node set can be gotten by calling
.BR numa_get_membind().
Bits in the
.I tonodes
mask can be set by calls to
.BR numa_bitmask_setbit().

.BR numa_error ()
is a
.I libnuma
internal function that can be overridden by the
user program.
This function is called with a
.I char *
argument when a
.I libnuma
function fails.
Overriding the library internal definition
makes it possible to specify a different error handling strategy
when a
.I libnuma
function fails. It does not affect
.BR numa_available ().
The
.BR numa_error ()
function defined in
.I libnuma
prints an error on
.I stderr
and terminates
the program if
.I numa_exit_on_error
is set to a non-zero value.
The default value of
.I numa_exit_on_error
is zero.

.BR numa_warn ()
is a
.I libnuma
internal function that can be also overridden
by the user program.
It is called to warn the user when a
.I libnuma
function encounters a non-fatal error.
The default implementation
prints a warning to
.IR stderr .
The first argument is a unique
number identifying each warning. After that there is a
.BR printf (3)-style
format string and a variable number of arguments.
.I numa_warn
exits the program when
.I numa_exit_on_warn
is set to a non-zero value.
The default value of
.I numa_exit_on_warn
is zero.

.SH Compatibility with libnuma version 1
Binaries that were compiled for libnuma version 1 need not be re-compiled
to run with libnuma version 2.
.br
Source codes written for libnuma version 1 may be re-compiled without
change with version 2 installed. To do so, in the code's Makefile add
this option to CFLAGS:  -DNUMA_VERSION1_COMPATIBILITY

.SH THREAD SAFETY
.I numa_set_bind_policy
and
.I numa_exit_on_error
are process global. The other calls are thread safe.

memory policy
.SH DESCRIPTION
.B numactl
runs processes with a specific NUMA scheduling or memory placement policy.
The policy is set for command and inherited by all of its children.
In addition it can set persistent policy for shared memory segments or files.
.PP
Use -- before command if using command options that could be confused
with numactl options.
.PP
.I nodes
may be specified as N,N,N or  N-N or N,N-N or  N-N,N-N and so forth.
Relative
.I nodes
may be specified as +N,N,N or  +N-N or +N,N-N and so forth. The + indicates that
the node numbers are relative to the process' set of allowed nodes in its
current cpuset.
A !N-N notation indicates the inverse of N-N, in other words all nodes
except N-N.  If used with + notation, specify !+N-N. When
.I same
is specified the previous nodemask specified on the command line is used.
all means all nodes in the current cpuset.
.PP
Instead of a number a node can also be:
.TS
tab(|);
l l.
netdev:DEV|The node connected to network device DEV.
file:PATH |The node the block device of PATH.
ip:HOST   |The node of the network device of HOST
block:PATH|The node of block device PATH
pci:[seg:]bus:dev[:func]|The node of a PCI device.
.TE

Note that block resolves the kernel block device names only
for udev names in /dev use
.I file:
.TP
Policy settings are:
.TP
.B \-\-all, \-a
Unset default cpuset awareness, so user can use all possible CPUs/nodes
for following policy settings.
.TP
.B \-\-interleave=nodes, \-i nodes
Set a memory interleave policy. Memory will be allocated using round robin
on
.I nodes.
When memory cannot be allocated on the current interleave target fall back
to other nodes.
Multiple nodes may be specified on --interleave, --membind and --cpunodebind.
.TP
.B \-\-membind=nodes, \-m nodes
Only allocate memory from nodes.  Allocation will fail when there
is not enough memory available on these nodes.
.I nodes
may be specified as noted above.
.TP
.B \-\-cpunodebind=nodes, \-N nodes
Only execute
.I command
on the CPUs of
.I nodes. 
Note that nodes may consist of multiple CPUs.
.I nodes
may be specified as noted above.
.TP
.B \-\-physcpubind=cpus, \-C cpus
Only execute
.I process
on
.I cpus.
This accepts cpu numbers as shown in the
.I processor
fields of 
.I /proc/cpuinfo,
or relative cpus as in relative to the current cpuset.
You may specify "all", which means all cpus in the current cpuset.
Physical
.I cpus
may be specified as N,N,N or  N-N or N,N-N or  N-N,N-N and so forth.
Relative
.I cpus
may be specified as +N,N,N or  +N-N or +N,N-N and so forth. The + indicates that
the cpu numbers are relative to the process' set of allowed cpus in its
current cpuset.
A !N-N notation indicates the inverse of N-N, in other words all cpus
except N-N.  If used with + notation, specify !+N-N.
.TP
.B \-\-localalloc, \-l 
Try to allocate on the current node of the process, but if memory cannot be allocated there fall back to other nodes.
.TP
.B \-\-preferred=node, \-p node
Preferably allocate memory on 
.I node,
but if memory cannot be allocated there fall back to other nodes.
This option takes only a single node number.
Relative notation may be used.
.TP
.B \-\-balancing, \-b
Enable Linux kernel NUMA balancing for the process if it is supported by kernel.
This should only be used with
.I \-\-membind, \-m
only, otherwise ignored.
.TP
.B \-\-preferred-many=nodes, \-P nodes
Preferably allocate memory on
.I nodes,
but if memory cannot be allocated there fall back to other nodes.
This option takes a mask of preferred nodes where the closest node to local is
considered most preferred.
Relative notation may be used.
.TP
.B \-\-show, \-s
Show NUMA policy settings of the current process. 
.TP
.B \-\-hardware, \-H
Show inventory of available nodes on the system. When the
.B \-\-cpu-compress
option is set show cpu ranges. This is not default not break any existing scripts.
.TP 0
Numactl can set up policy for a SYSV shared memory segment or a file in shmfs/hugetlbfs.
.TP
.B \-\-version
print the version of the numactl package and exit.
.TP
 
The following policy settings are persistent and will be used by
all mappings from that shared memory. The order of options matters here.
The specification must at least include either of 
.I \-\-shm, 
.I \-\-shmid, 
.I \-\-file
to specify the shared memory segment or file and a memory policy like described 
above (
.I \-\-interleave, 
.I \-\-localalloc, 
.I \-\-preferred,
.I \-\-preferred-many,
.I \-\-membind
).
.TP
.B \-\-huge
When creating a SYSV shared memory segment use huge pages.
Only valid before \-\-shmid or \-\-shm
.TP 
.B \-\-offset
Specify offset into the shared memory segment. Default 0. 
Valid units are 
.I m
(for MB), 
.I g 
(for GB), 
.I k 
(for KB),
otherwise it specifies bytes.
.TP
.B \-\-strict
Give an error when a page in the policied area in the shared memory
segment already was faulted in with a conflicting policy. Default
is to silently ignore this.
.TP
.B \-\-shmmode shmmode
Only valid before \-\-shmid or \-\-shm
When creating a shared memory segment set it to numeric mode 
.I shmmode.
.TP
.B \-\-length length
Apply policy to 
.I length 
range in the shared memory segment or make 
the segment length long
Default is to use the remaining length 
Required when a shared memory segment is created and specifies the length
of the new segment then. Valid units are 
.I m
(for MB), 
.I g 
(for GB), 
.I k 
(for KB),
otherwise it specifies bytes.
.TP
.B \-\-shmid id
Create or use a shared memory segment with numeric ID
.I id
.TP 
.B \-\-shm shmkeyfile
Create or use a shared memory segment, with the ID generated
using 
.I ftok(3) 
from shmkeyfile
.TP
.B \-\-file tmpfsfile
Set policy for a file in tmpfs or hugetlbfs
.TP
.B \-\-touch
Touch pages to enforce policy early. Default is to not touch them, the policy
is applied when an applications maps and accesses a page.
.TP
.B \-\-dump
Dump policy in the specified range.
.TP
.B \-\-dump-nodes
Dump all nodes of the specific range (very verbose!)
.TP
Valid node specifiers
.TS
tab(:);
l l. 
all:All nodes
number:Node number
number1{,number2}:Node number1 and Node number2
number1-number2:Nodes from number1 to number2
! nodes:Invert selection of the following specification.
.TE
.SH EXAMPLES
numactl \-\-physcpubind=+0-4,8-12 myapplic arguments
Run myapplic on cpus 0-4 and 8-12 of the current cpuset.

numactl \-\-interleave=all bigdatabase arguments
Run big database with its memory interleaved on all CPUs.

numactl \-\-cpunodebind=0 \-\-membind=0,1 process
Run process on node 0 with memory allocated on node 0 and 1.

numactl \-\-cpunodebind=0 \-\-membind=0,1 -- process -l
Run process as above, but with an option (-l) that would be confused with
a numactl option.

numactl \-\-cpunodebind=0 \-\-balancing \-\-membind=0,1 process
Run process on node 0 with memory allocated on node 0 and 1.  Optimize the
page placement with Linux kernel NUMA balancing mechanism if possible.

numactl \-\-cpunodebind=netdev:eth0 \-\-membind=netdev:eth0 network-server
Run network-server on the node of network device eth0 with its memory
also in the same node.

numactl \-\-preferred=1 numactl \-\-show
Set preferred node 1 and show the resulting state.

numactl \-\-preferred-many=0x3 numactl \-\-show
Set preferred nodes 1 and 2, and show the resulting state.

numactl --length 1g --shm /tmp/shmkey --interleave=all
Interleave all of the sysv shared memory region of size 1g specified by
/tmp/shmkey over all nodes.

Place a tmpfs file on 2 nodes:
  numactl --membind=2 dd if=/dev/zero of=/dev/shm/A bs=1M count=1024
  numactl --membind=3 dd if=/dev/zero of=/dev/shm/A seek=1024 bs=1M count=1024

numactl --localalloc /dev/shm/file
Reset the policy for the shared memory file 
.I file
to the default localalloc policy.
.SH NOTES
Requires a NUMA policy aware kernel.

Command is not executed using a shell. If you want to use shell metacharacters
in the child use sh -c as wrapper.

Setting policy for a hugetlbfs file does currently not work because
it cannot be extended by truncate.

Shared memory segments larger than numactl's address space cannot 
be completely policied. This could be a problem on 32bit architectures.
Changing it piece by piece may work.

The old
.I --cpubind
which accepts node numbers, not cpu numbers, is deprecated
and replaced with the new 
.I --cpunodebind
and 
.I --physcpubind
options.

.SH FILES
.I /proc/cpuinfo
for the listing of active CPUs. See 
.I proc(5)
for details.

.I /sys/devices/system/node/node*/numastat
for NUMA memory hit statistics.

.br
.SH "DESCRIPTION"
.LP
.B numastat 
with no command options or arguments at all, displays per-node NUMA hit and
miss system statistics from the kernel memory allocator.  This default
\fBnumastat\fP behavior is strictly compatible with the previous long-standing
\fBnumastat\fP perl script, written by Andi Kleen.  The default \fBnumastat\fP
statistics shows per-node numbers (in units of pages of memory) in these categories:
.LP
.B numa_hit 
is memory successfully allocated on this node as intended.
.LP
.B numa_miss
is memory allocated on this node despite the process preferring some different node. Each
.I numa_miss
has a
.I numa_foreign
on another node.
.LP
.B numa_foreign
is memory intended for this node, but actually allocated on some different node.  Each
.I numa_foreign
has a
.I numa_miss
on another node.
.LP
.B interleave_hit
is interleaved memory successfully allocated on this node as intended.
.LP
.B local_node
is memory allocated on this node while a process was running on it.
.LP
.B other_node
is memory allocated on this node while a process was running on some other node.
.LP
Any supplied options or arguments with the \fBnumastat\fP command will
significantly change both the content and the format of the display.  Specified
options will cause display units to change to megabytes of memory, and will
change other specific behaviors of \fBnumastat\fP as described below.
.LP
Memory usage information reflects the resident pages on the system.
.SH "OPTIONS"
.LP
.TP
\fB\-c\fR
Minimize table display width by dynamically shrinking column widths based on
data contents.  With this option, amounts of memory will be rounded to the
nearest megabyte (rather than the usual display with two decimal places).
Column width and inter-column spacing will be somewhat unpredictable with this
option, but the more dense display will be very useful on systems with many
NUMA nodes.
.TP
\fB\-m\fR
Show the meminfo-like system-wide memory usage information.  This option
produces a per-node breakdown of memory usage information similar to that found
in /proc/meminfo.
.TP
\fB\-n\fR
Show the original \fBnumastat\fP statistics info.  This will show the same
information as the default \fBnumastat\fP behavior but the units will be megabytes of
memory, and there will be other formatting and layout changes versus the
original \fBnumastat\fP behavior.
.TP
\fB\-p\fR <\fBPID\fP> or <\fBpattern\fP>
Show per-node memory allocation information for the specified PID or pattern.
If the \-p argument is only digits, it is assumed to be a numerical PID.  If
the argument characters are not only digits, it is assumed to be a text
fragment pattern to search for in process command lines.  For example,
\fBnumastat -p qemu\fP will attempt to find and show information for processes
with "qemu" in the command line.  Any command line arguments remaining after
\fBnumastat\fP option flag processing is completed, are assumed to be
additional <\fBPID\fP> or <\fBpattern\fP> process specifiers.  In this sense,
the \fB\-p\fP option flag is optional: \fBnumastat qemu\fP is equivalent to
\fBnumastat -p qemu\fP
.TP
\fB\-s[<node>]\fR
Sort the table data in descending order before displaying it, so the biggest
memory consumers are listed first.  With no specified <node>, the table will be
sorted by the total column.  If the optional <node> argument is supplied, the
data will be sorted by the <node> column.  Note that <node> must follow the
\fB\-s\fP immediately with no intermediate white space (e.g., \fBnumastat
\-s2\fP). Because \fB\-s\fP can allow an optional argument, it must always be
the last option character in a compound option character string. For example,
instead of \fBnumastat \-msc\fP (which probably will not work as you expect),
use \fBnumastat \-mcs\fP
.TP
\fB\-v\fR
Make some reports more verbose.  In particular, process information for
multiple processes will display detailed information for each process.
Normally when per-node information for multiple processes is displayed, only
the total lines are shown.
.TP
\fB\-V\fR
Display \fBnumastat\fP version information and exit.
.TP
\fB\-z\fR
Skip display of table rows and columns of only zero valuess.  This can be used
to greatly reduce the amount of uninteresting zero data on systems with many
NUMA nodes.  Note that when rows or columns of zeros are still displayed with
this option, that probably means there is at least one value in the row or
column that is actually non-zero, but rounded to zero for display.
.SH NOTES 
\fBnumastat\fP attempts to fold each table display so it will be conveniently
readable on the output terminal.  Normally a terminal width of 80 characters is
assumed.  When the \fBresize\fP command is available, \fBnumastat\fP attempts
to dynamically determine and fine tune the output tty width from \fBresize\fP
output.  If \fBnumastat\fP output is not to a tty, very long output lines can
be produced, depending on how many NUMA nodes are present.  In all cases,
output width can be explicitly specified via the \fBNUMASTAT_WIDTH\fP
environment variable.  For example, \fBNUMASTAT_WIDTH=100  numastat\fP.  On
systems with many NUMA nodes, \fBnumastat \-c \-z ....\fP can be very helpful
to selectively reduce the amount of displayed information.

.LP
The original \fBnumastat\fP perl script was written circa 2003 by Andi Kleen
<andi.kleen@intel.com>.  The current \fBnumastat\fP program was written in 2012
by Bill Gray <bgray@redhat.com> to be compatible by default with the original,
and to add options to display per-node system memory usage and per-node process
memory allocation.

Historical note: From approximately 2003 to 2012, numastat was a perl script
written by Andi Kleen to display the /sys/devices/system/node/node<N>/numastat
statistics. In 2012, numastat was rewritten as a C program by Red Hat to
display per-node memory data for applications and the system in general,
while also remaining strictly compatible by default with the original numastat.
A copy of the original numastat perl script is included for reference at the
end of this file.

/*
 * Program: Stream
 * Programmer: Joe R. Zagar
 * Revision: 4.0-BETA, October 24, 1995
 * Original code developed by John D. McCalpin
 *
 * This program measures memory transfer rates in MB/s for simple
 * computational kernels coded in C.  These numbers reveal the quality
 * of code generation for simple uncacheable kernels as well as showing
 * the cost of floating-point operations relative to memory accesses.
 *
 * INSTRUCTIONS:
 *
 *	1) Stream requires a good bit of memory to run.  Adjust the
 *          value of 'N' (below) to give a 'timing calibration' of
 *          at least 20 clock-ticks.  This will provide rate estimates
 *          that should be good to about 5% precision.
 *
 * Hacked by AK to be a library
 */

long N = 8000000;
#define NTIMES	10
#define OFFSET	0

/*
 *	3) Compile the code with full optimization.  Many compilers
 *	   generate unreasonably bad code before the optimizer tightens
 *	   things up.  If the results are unreasonably good, on the
 *	   other hand, the optimizer might be too smart for me!
 *
 *         Try compiling with:
 *               cc -O stream_d.c second_wall.c -o stream_d -lm
 *
 *         This is known to work on Cray, SGI, IBM, and Sun machines.
 *
 *
 *	4) Mail the results to mccalpin@cs.virginia.edu
 *	   Be sure to include:
 *		a) computer hardware model number and software revision
 *		b) the compiler flags
 *		c) all of the output from the test case.
 * Thanks!

Various simple test scripts to verify some parts of the NUMA API.

To do a full regression test run make test

You should have at least two nodes on a NUMA system for the test suite.

The tests in regress assume that there is enough memory free on nodes 0/1.
They consider PREFERRED/INTERLEAVE not hitting the first choice node an 
error.

They also require a relatively idle machine to avoid too much
noise from memory allocation from other processes. Without
that regress1 might fail.

You can run the tests under valgrind with VALGRIND=valgrind make test
Older valgrind versions incorrectly report a uninitialized byte error
on set_mempolicy. That is a false positive.

TBD: more detailed unit tests for mbind / shm / {get,set}_mempolicy
Currently everything is tested using numactl only.

# version node are effectively bound to an unspecified base version of
# the library. It is possible to bind all otherwise unspecified symbols
# to a given version node using `global: *' somewhere in the version script.

# The interfaces at the "v1" level.
# At this level we present these functions to the linker (and thus to an
# application).
# Any functions not defined in the global list (i.e. "local") will be internal
# to the library (i.e. not exported but used within the library).
# Thus the real function names, "numa_bind_v1" etc, are local and won't
# be known to the linker.
