- Update to version 0.3.3
common:
* thread memory allocation has been switched back to the method used before version 0.3.1 due to unexpected problems caused by the new code under some circumstances.
* LAPACK PR272 has been integrated, which fixes spurious errors in DSYEVR and related functions caused by missing conversion from ILAENV to ILAENV_2STAGE in several _2stage routines.
x86_64
* added AVX512 implementations of SDOT, DDOT, SAXPY, DAXPY, DSCAL, DGEMVN and DSYMVL
* added a workaround for a cygwin issue that prevented compilation of AVX512 code

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
