- Update to version 0.3.8 common: * LAPACK has been updated to 3.9.0 (plus patches up to January 2nd, 2020) * CMAKE support has been improved in several areas including cross-compilation * A thread race condition in the GEMM3M kernels was resolved * The "generic" (plain C) gemm beta kernel used by many targets has been sped up * An optimized version of the LAPACK trtrs functions has been added * An incompatibilty between the LAPACK tests and the OpenBLAS implementation of XERBLA was resolved, removing the numerous warnings about wrong error exits in the former * Support for NetBSD has been added * Support for compilation with g95 and non-GNU versions of ld has been improved * Compilation with (upcoming) gcc 10 is now supported power: * Worked around miscompilation of several POWER8 and POWER9 kernels by older versions of gcc * Added support for big-endian POWER8 and for compilation on AIX * Corrected bugs in the big-endian support for PPC440 and PPC970 * DYNAMIC_ARCH support is now available in CMAKE builds as well armv8: * Performance of DGEMM_BETA and SGEMM_NCOPY has been improved * Compilation for 32bit works again * Performance of the RPCC function has been improved * Improved performance on small systems * DYNAMIC_ARCH support is now available in CMAKE builds as well * Cross-compilation from OSX to IOS was simplified x86-64: * A new AVX512 DGEMM kernel was added and the AVX512 SGEMM kernel was significantly improved * Optimized AVX512 kernels for CGEMM and ZGEMM have been added * AVX2 kernels for STRMM, SGEMM, and CGEMM have been significantly OBS-URL: https://build.opensuse.org/request/show/772619 OBS-URL: https://build.opensuse.org/package/show/science/openblas?expand=0&rev=87 |

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
