- Recreate old library scheme for existing products: It turned out the new scheme on existing systems has been causing package breakages. - Do not generate baselibs.conf for HPC builds. - Add support for gcc11 & 12. - For SLE/Leap on x86_64 and s390x do not mix compiler versions as this will make the gfortran ABI version inconsistent. Instead use the stock compiler and set the list of kernels for x86_64 cores explicitly as Cooperlake requires compiler intrinsics which are not provided by gcc 7. - Require at least 7G of disk space for building.

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
