- updated to version 5.3.5, changes are
* Fixed 2x2 pivots bug from 5.3.4 release in MPI LDLT factorization
* Fixed ICNTL(8)=-2 option during analysis (code and documentation)
* Fixed a rare bug (segfault) related to dynamic storage management on numerically difficult matrices
* Fixed a rare deadlock in BLR for symmetric matrices
* Fixed an uninitialized variable (which could lead to incorrect -19 error)
* Minor fix in userguide (CNTL(1) vs. ICNTL(1) in ICNTL(36) description)
* Fixed a possible runtime issue during solve, related to "TO_PROCESS" array
* Assume ilp64 MPI interface only applies to Fortran in c_example.c
* Note on gfortran-10 compilation added
* Avoid intent on pointers (F2003-only)
* More robust multithreading for matrix reformatting (arrowheads)
* Fixed ICNTL(31) interpretation in case of repeated analysis
* Fixed multiple mpif.h inclusion (distributed rhs, ifort+openmpi)
* Fixed computation of effectively used memory statistics
* Improved multithreaded performance of BLR backward solve
* Fixed return code in build_mumps_int_def.c + openmp compilation (pgi)
* Forbid a loop vectorization in [sdcz]sol_c.F (segfault with ifort)
* New feature: distributed right-hand sides
* Improved time for arrowheads construction (single MPI case, mainly)
* C interface: ability to know if MUMPS_INT is 64-bit from include file
* Improved BLR performance when CNTL(1)=0.0 and ICNTL(36)=1
* Fixed INFO(34),INFO(35),INFO(37),INFO(38) on processes with rank > 0
* More portable MPI_IS_IN_PLACE feature in libseq
* Fixed determinant computation when Cholesky ScaLapack is used
* Information on advancement (flops done) on each MPI process
* Allow rhs_sparse and irhs_sparse to be unassociated if nz_rhs=0
* Fixed INFO(30) and INFO(31) computation on MPI processes with rank > 0
* OMP collapsed loops: avoid FIRSTPRIVATE on internal loop bound (for pgi)
* Fix for compilers not freeing local allocatable arrays (64-bit metis)
