- Change library name suffix * drop openblas-soname.patch - Add RPM %post script for manual BLAS/LAPACK update-alternatives configuration update - Use update-alternatives mechanism for OpenBLAS variants (serial, openmp, pthreads). pthreads variant is default for x86 and x86_64, OpenMP for other architectures. - Fix build on ARM64 * openblas-arm64-build.patch - Add update-alternatives mechanism for CBLAS - Provide cmake module - Delete info about host cpu from openblas_config.h for dynamic arch - Add update-alternatives to 'preup' and 'post' requires list for libraries - Add README.SUSE OBS-URL: https://build.opensuse.org/request/show/322040 OBS-URL: https://build.opensuse.org/package/show/openSUSE:Factory/openblas?expand=0&rev=9
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
