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
