- The toolchain and 'make' in TW have been updated to handle parallel makes spawned by gcc (for LTO optimization) properly. Thus, remove restrictions. - Disable lto when linking test programs to speeds up 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
