Hello,
Are blas/lapack running in parallel by default?
I have openmp installed
Do I need to recompile ?
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.
