- Update to version 0.3.27 (boo#1225869): General: * Added initial (generic) support for the `CSKY` architecture. * Capped the maximum number of threads used in `GEMM`, `GETRF` and `POTRF` to avoid creating underutilized or idle threads. * Sped up multithreaded `POTRF` on all platforms. * Added extension `openblas_set_num_threads_local()` that returns the previous thread count. * Re-evaluated the `SGEMV` and `DGEMV` load thresholds to avoid activating multithreading for too small workloads. * Improved the fallback code used when the precompiled number of threads is exceeded, and made it callable multiple times during the lifetime of an instance. * Added CBLAS interfaces for the BLAS extensions `?AMIN`,`?AMAX`, `CAXPYC` and `ZAXPYC`. * Fixed a potential buffer overflow in the interface to the `GEMMT` kernels. * Fixed use of incompatible pointer types in `GEMMT` and `C`/`ZAXPBY` as flagged by GCC-14. * Fixed unwanted case sensitivity of the character parameters in `?TRTRS` sped up the OpenMP thread management code. * Fixed sizing of logical variables in `INTERFACE64` builds of the C version of LAPACK. * Fixed inclusion of new LAPACK and LAPACKE functions from LAPACK 3.11 in the shared library. * Modified the error thresholds for `SGS`/`DGS` functions in the LAPACK testsuite to suppress spurious errors. * Added support for calling ?NRM2 with a negative increment value on all architectures. * Fixed handling of the `OPENBLAS_LOOPS` variable in several OBS-URL: https://build.opensuse.org/request/show/1179598 OBS-URL: https://build.opensuse.org/package/show/science/openblas?expand=0&rev=175 |

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
