Description Susi Lehtola 2010-02-14 08:37:21 UTC 
Hi,


numpy currently builds against reference BLAS and LAPACK. Please make numpy use ATLAS instead, which is faster by an order of magnitude or so. This has many important implications for whoever is using numpy in any sort of calculations.

To do this change BR: lapack-devel to BR: atlas-devel, and use e.g.

--with-blas="-L%{_libdir}/atlas -lf77blas -latlas"
--with-lapack="-L%{_libdir}/atlas -llapack"
