- Build PPC64LE libraries with the lastest gcc available to take advantage of instruction sets in later CPUs used in the CPU specific kernels (jsc#SLE-18143, bsc#1197721). For fortran use the stock compiler to avoid compatibility issues between different versions of libfortran. This is relevant for Leap/SLE only. It may be dropped once gcc < 10 is no longer supported. - Do the same for x86_64 on SLE to make sure Cooperlake support is built properly. - Remove: * Do-not-attempt-to-check-host-CPU-if-TARGET-is-set.patch * Create-independent-kernel-Makfile-configuration-when-building-DYNAMIC_ARCH.patch * For-DYNAMIC_ARCH-don-t-use-sbgemm_r-as-parameter.c-doesn-t-get-build.patch Instead, add from upstream: * Define-sbgemm_r-to-fix-DYNAMIC_ARCH-builds.patch * Remove-extraneous-and-wrong-definition-of-sbgemm_r-on-x86_64.patch * Fix-checks-for-AVX512-and-atomics.patch * Revert-AVX512-capability-check-from-PR-1980-moved-to-build.patch * Use-CC-and-full-command-line-instead-of-hard-coding-gcc-for-AVX512-checking.patch * Utilize-compiler-AVX512-capability-info-from-c_check-when-building-getarch.patch BLAS/LAPACK implementation (boo#1177260). 'openblas-common-devel' will provide the removed 'openblas-devel-headers' while the arch specific 'preferred' flavor will provide the removed 'openblas-devel'.

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
