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.
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..
I tried to modify existing RPM Spec file but without success.
Can EPEL team help provide such LAPACK packages linked to OpenBLAS?
Not easily. Because lapack is shipped by RHEL/CentOS in the base OS,
we do not provide packages which would overwrite them. What it would
require instead is that someone would write a spec file which was
parallel or similarly installable with the base lapack. This
lapack-openblas would need to be reviewed and built by either the
owner of the lapack command or someone who is knows the package well
enough not to cause problems with the default lapack. If those steps
are done then it could be put in the EPEL package repository.
The owner of the lapack package in Fedora is spot(a)fedoraproject.org
and he would be the person for you to start the conversation with.
