- Update to versiom 0.3.5
common:
* Loop unrolling in TRMV has been enabled again.
* A domain error in the thread workload distribution for SYRK
has been fixed.
* gmake builds will now automatically add -fPIC to the build
options if the platform requires it.
* A pthreads key leakage (and associate crash on dlclose) in
the USE_TLS codepath was fixed.
* Building of the utest cases on systems that do not provide
an implementation of complex.h was fixed.
x86_64:
* The SkylakeX code was changed to compile on OSX.
* Unwanted application of the -march=skylake-avx512 option
to the common code parts of a DYNAMIC_ARCH build was fixed.
* Improved performance of SGEMM for small workloads on Skylake X.
* Performance of SGEMM and DGEMM was improved on Haswell.
armv8:
* A configuration error that broke the CNRM2 kernel was corrected.
* Compilation of the GEMM kernels with CMAKE was fixed.
* DYNAMIC_ARCH builds are now available with CMAKE as well.
* Using CMAKE for cross-compilation to the new cpu TARGETs
introduced in 0.3.4 now works.
power:
* A problem in cpu autodetection for AIX has been corrected.

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
