- Update to v0.3.21:
* general:
- Updated the included LAPACK to Reference-LAPACK release 3.10.1
- when no Fortran compiler is available, OpenBLAS builds will now automatically
- function LAPACKE_lsame is now annotated with the GCC attribute "const" to aid static analyzers
- added USE_TLS to the list of options reported by the openblas_get_config() function
- added SYMBOLPREFIX/SYMBOLSUFFIX handling for LAPACK 3.10.0 functions added in 0.3.20
- reverted OpenMP threadpool behaviour in the exec_blas call to its state before 0.3.11, that is
the threadpool will no longer grow or shrink on demand as the overhead for this is too big at least with
GNU OpenMP. The adaptive behaviour introduced in 0.3.11 can still be requested at runtime by setting
the environment variable OMP_ADAPTIVE
- worked around spurious STFSM/CTFSM errors reported by the LAPACK testsuite
* x86_64:
- fixed determination of compiler support for AVX512 and removed the 0.3.19
- workaround for building SKYLAKEX kernels on Sandybridge hardware
- fixed compilation for the SKYLAKEX target with gcc 6
- fixed compilation of the SkyLakeX small matrix GEMM kernels with LLVM or ICC
- added support for the Zhaoxin/Centaur KH40000 cpu
- fixed a potential crash in the ZSYMV kernel used for all targets except generic
* POWER:
- worked around an overflow error in the POWER6 DNRM2 kernel
- fixed compilation on PPC440
- fixed a performance regression in the level1 BLAS on POWER10
- fixed the POWER10 ZGEMM kernel
- fixed singlethreaded builds for POWER10
- fixed compilation of the POWER10 DGEMV kernel with older gcc versions
- enabled compilation of the BFLOAT16 kernels by default
- enabled the small matrix kernels by default for DYNAMIC_ARCH builds
- added a workaround for a miscompilation of the CDOT and ZDOT kernels by GCC 12
- Obsolete:

openSUSE specific packaging =========================== OpenBLAS provides optimized implementations of BLAS and LAPACK. openSUSE provides three variants: * Serial library (libopenblas_serial0) * With OpenMP support (libopenblas_openmp0) * With threading support (libopenblas_pthreads0) By defult openSUSE uses pthreads version on x86 systems and OpenMP for other architectures. On x86 systems OpenBLAS uses dynamic architectures support, so it contains all CPU-related optimizations. How to switch between the various BLAS/LAPACK implementations ============================================================= BLAS: sudo /usr/sbin/update-alternatives --config libblas.so.3 LAPACK: sudo /usr/sbin/update-alternatives --config liblapack.so.3 More information is available at: https://en.opensuse.org/openSUSE:Science_Linear_algebra_libraries
