I assume you want to improve performance of some computation. Many computational packages have been developed and testing with a particular BLAS implementation but may only document the Debian/Ubuntu alternatives mechanism. "dnf seach blas" will show you many options, including openblas and blis. The flexiblas package should allow you to change the choice of BLAS library at run time < https://fedoraproject.org/wiki/Changes/FlexiBLAS_as_BLAS/LAPACK_manager> https://loveshack.fedorapeople.org/blas-subversion.html is old, but does mention some of the issues. -- George N.
