- Update to version 0.3.9
common:
* Fixed a miscompilation of the GETRF functions with CMAKE
The size of the memory buffer used for splitting GEMM tasks across
multiple threads can now be configured in the build system.
Imported bugfix 390 from LAPACK (missing NaN propagation in xCOMBSSQ)
POWER:
* fixed several compilation problems related to endianness and
ELF version support on POWER8 and POWER9.
* fixed misuse of the absolute value IAMIN/IAMAX in place of IMIN/IMAX
* fixed a race condition in the level3 blas code
MIPS64:
* fixed misuse of the absolute value IAMIN/IAMAX in place of IMIN/IMAX
ARMV7:
* fixed a race condition in the level3 blas code
* fixed a compilation problem on Android
ARMV8:
* Added support for Ampere EMAG8180
* Added support for Neoverse N1
improved performance of the blas_lock function
fixed a race condition in the level3 blas code
* Fixed a performance regression on TSV110 servers
x86_64:
* Fixed a long-standing error with undeclared register clobbers in
the DSCAL microkernel for Haswell,SkylakeX and Zen exposed by gcc9.2
* Fixed a long-standing bug in the SSE implementation of the IAMAX functions
* Fixed a cmake build failure with DYNAMIC_ARCH on x86_64
* Fixed an oversight in the cpu detection code for Intel Goldmont+,
Cannon Lake and Ice Lake

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
