<patchinfo incident="33050"> <issue tracker="bnc" id="1221813">[RN, OpenBLAS] Update to version 0.3.25</issue> <issue tracker="jsc" id="PED-7926"/> <issue tracker="jsc" id="PED-7927"/> <packager>eeich</packager> <rating>important</rating> <category>feature</category> <summary>Feature update for openblas</summary> <description>This update for openblas fixes the following issues: openblas was updated from version 0.3.21 to version 0.3.25 (jsc#PED-7926, jsc#PED-7927, bsc#1221813): - Changes in version 0.3.25: * General: + Improved the error message shown on exceeding the maximum thread count + Improved the code to add supplementary thread buffers in case of overflow + Fixed a potential division by zero in `?ROTG` + Improved the `?MATCOPY` functions to accept zero-sized rows or columns + Corrected empty prototypes in function declarations + cleaned up unused declarations in the f2c-converted versions of the LAPACK sources + Improved link line rewriting to avoid mixed libgomp/libomp builds with clang&gfortran + imported the following changes from the upcoming release 3.12 of Reference-LAPACK: LAPACK PR 900, LAPACK PR 904, LAPACK PR 907, LAPACK PR 909, LAPACK PR 926, LAPACK PR 927, LAPACK PR 928 & 930 * Architecture x86-64: + Fixed capability-based fallback selection for unknown cpus in `DYNAMIC_ARCH` + Added AVX512 optimizations for `?ASUM` on Intel Sapphire Rapids and Cooper Lake * Architecture ARM64: + Fixed building with XCODE 15 + Fixed building on A64FX and Cortex A710/X1/X2 + increased the default buffer size for recent arm server cpus * Architecture POWER PC: + Added support for `DYNAMIC_ARCH` builds with clang + Fixed union declaration in the `BFLOAT16` test case - Changes in version 0.3.24: * General: + Declared the arguments of `cblas_xerbla` as `const` (in accordance with the reference implementation and others, the previous discrepancy appears to have dated back to GotoBLAS) + Fixed the implementation of `?GEMMT` that was added in 0.3.23 + made cpu-specific `SWITCH_RATIO` parameters for GEMM available to `DYNAMIC_ARCH` builds + Fixed missing `SSYCONVF` function in the shared library + Fixed parallel build logic used with gmake + Fixed several issues with the handling of runtime limits on the number of OPENMP threads + Corrected the error code returned by `SGEADD`/`DGEADD` when LDA is too small + Corrected the error code returned by `IMATCOPY` when LDB is too small + Updated `?NRM2` to support negative increment values (as introduced in release 3.10.0 of the Reference BLAS) + Updated `?ROTG` to use the safe scaling algorithm introduced in release 3.10.0 of the Reference BLAS + Fixed OpenMP builds with CLANG for the case where libomp is not in a standard location + Fixed a potential overwrite of unrelated memory during thread initialisation on startup + Fixed a potential integer overflow in the multithreading threshold for `?SYMM`/`?SYRK` + Fixed build of the LAPACKE interfaces for the LAPACK 3.11.0 `?TRSYL` functions added in 0.3.22 + Applied additions and corrections from the development branch of Reference-LAPACK: - Fixed actual arguments passed to a number of LAPACK functions (from Reference-LAPACK PR 885) - Fixed workspace query results in LAPACK `?SYTRF`/`?TRECV3` (from Reference-LAPACK PR 883) - Fixed derivation of the UPLO parameter in `LAPACKE_?larfb` (from Reference-LAPACK PR 878) - Fixed a crash in LAPACK `?GELSDD` on `NRHS=0` (from Reference-LAPACK PR 876) - Added new LAPACK utility functions `CRSCL` and `ZRSCL` (from Reference-LAPACK PR 839) - Corrected the order of eigenvalues for 2x2 matrices in `?STEMR` (Reference-LAPACK PR 867) - Removed spurious reference to OpenMP variables outside OpenMP contexts (Reference-LAPACK PR 860) - Updated file comments on use of `LAMBDA` variable in LAPACK (Reference-LAPACK PR 852) - Fixed documentation of LAPACK `SLASD0`/`DLASD0` (Reference-LAPACK PR 855) - Fixed confusing use of "minor" in LAPACK documentation (Reference-LAPACK PR 849) - Added new LAPACK functions ?GEDMD for dynamic mode decomposition (Reference-LAPACK PR 736) - Fixed potential stack overflows in the `EIG` part of the LAPACK testsuite (Reference-LAPACK PR 854) - Applied small improvements to the variants of Cholesky and QR functions (Reference-LAPACK PR 847) - Removed unused variables from LAPACK `?BDSQR` (Reference-LAPACK PR 832) - Fixed a potential crash on allocation failure in LAPACKE `SGEESX`/`DGEESX` (Reference-LAPACK PR 836) - Added a quick return from `SLARUV`/`DLARUV` for N < 1 (Reference-LAPACK PR 837) - Updated function descriptions in LAPACK `?GEGS`/`?GEGV` (Reference-LAPACK PR 831) - Improved algorithm description in `?GELSY` (Reference-LAPACK PR 833) - Fixed scaling in LAPACK `STGSNA`/`DTGSNA` (Reference-LAPACK PR 830) - Fixed crash in `LAPACKE_?geqrt` with row-major data (Reference-LAPACK PR 768) - Added LAPACKE interfaces for `C/ZUNHR_COL` and `S/DORHR_COL` (Reference-LAPACK PR 827) - Added error exit tests for `SYSV`/`SYTD2`/`GEHD2` to the testsuite (Reference-LAPACK PR 795) - Fixed typos in LAPACK source and comments (Reference-LAPACK PRs 809,811,812,814,820) - Adopt refactored `?GEBAL` implementation (Reference-LAPACK PR 808) * Architecture x86_64: + Added cpu model autodetection for Intel Alder Lake N + Added activation of the AMX tile to the Sapphire Rapids `SBGEMM` kernel + worked around miscompilations of GEMV/SYMV kernels by gcc's tree-vectorizer + Fixed runtime detection of Cooperlake and Sapphire Rapids in `DYNAMIC_ARCH` + Fixed feature-based cputype fallback in `DYNAMIC_ARCH` + Corrected `ZAXPY` result on old pre-AVX hardware for the `INCX=0` case + Fixed a potential use of uninitialized variables in ZTRSM * Architecture ARMV8: + implemented SWITCH_RATIO parameter for improved GEMM performance on Neoverse + activated SVE SGEMM and DGEMM kernels for Neoverse V1 + Improved performance of the SVE CGEMM and ZGEMM kernels on Neoverse V1 + Improved kernel selection for the ARMV8SVE target and added it to `DYNAMIC_ARCH` + Fixed runtime check for SVE availability in `DYNAMIC_ARCH` builds to take OS or container restrictions into account + Fixed a potential use of uninitialized variables in ZTRSM * Architecture POWER PC: + Fixed compiler warnings in the POWER10 SBGEMM kernel - Changes in version 0.3.23: * General: + Fixed a serious regression in `GETRF`/`GETF2` and `ZGETRF`/`ZGETF2` where subnormal but nonzero data elements triggered the singularity flag + Fixed a long-standing bug in `CSPR`/`ZSPR` in single-threaded operation + for cases where elements of the X vector are real numbers (or complex with only the real part zero) * Architecture x86_64: + Added further CPUID values for Intel Raptor Lake - Changes in version 0.3.22: * General: + Updated the included LAPACK to Reference-LAPACK release 3.11.0 plus post-release corrections and improvements + Added a threshold for multithreading in `SYMM`, `SYMV` and `SYR2K` + Increased the threshold for multithreading in `SYRK` + OpenBLAS no longer decreases the global `OMP_NUM_THREADS` when it exceeds the maximum thread count the library was compiled for. + Fixed `?GETF2` potentially returning `NaN` with tiny matrix elements + Fixed `openblas_set_num_threads` to work in `USE_OPENMP` builds. + Fixed cpu core counting in `USE_OPENMP` builds returning the number of OMP "places" rather than cores + Fixed stride calculation in the optimized small-matrix path of complex `SYR` + Fixed building of Reference-LAPACK with recent gfortran + Added new environment variable `OPENBLAS_DEFAULT_NUM_THREADS` + Added a GEMV-based implementation of `GEMMT` * Architecture x86_64: + Added autodetection of Intel Raptor Lake cpu models + Added SSCAL microkernels for Haswell and newer targets + Improved the performance of the Haswell DSCAL microkernel + Added CSCAL and ZSCAL microkernels for SkylakeX targets + Fixed detection of gfortran and Cray CCE compilers + Fixed runtime selection of COOPERLAKE in `DYNAMIC_ARCH` builds + Worked around gcc/llvm using risky FMA operations in CSCAL/ZSCAL * Architecture ARMV8: + Fixed cross-compilation to CortexA53 with CMAKE + Fixed compilation with CMAKE and "Arm Compiler for Linux 22.1" + Added cpu autodetection for Cortex X3 and A715 + Fixed conditional compilation of SVE-capable targets in `DYNAMIC_ARCH` + sped up SVE kernels by removing unnecessary prefetches + Improved the GEMM performance of Neoverse V1 + Added SVE kernels for SDOT and DDOT + Added an SBGEMM kernel for Neoverse N2 + Improved cpu-specific compiler option selection for Neoverse cpus + Added support for setting `CONSISTENT_FPCSR` </description> </patchinfo>
