Hi,
I try to compile and install some programs in CentOS 7 which depends on
LAPACK.
I hope to use LAPACK linked to OpenBLAS, which gives better performance
compared to Reference BLAS.
OpenBLAS provides its own LAPACK, which has some optimizations and is
probably more recent than RHEl's -- I haven't checked. You can just
link against that, and the EPEL OB rpms are recent.
But in CentOS 7, LAPACK packages is linked to Netlib BLAS, not
OpenBLAS.
As far as I know, in Arch Linux, their team provides such package
https://aur.archlinux.org/packages/openblas-lapack/
which provides LAPACK library linked to OpenBLAS.
So I guess it is possible to have such package in CentOS, too.
I know that I can just compile LAPACK + OpenBLAS by myself rather than
installing pre-compiled packages, but it would be better to have rpm files
instead..
The linear algebra situation in RHEl/Fedora is unfortunate, but you can
hack around linkage with inefficient BLAS/LAPACK
