Hi,

I would like to propose start of High performance computing (HPC) SIG. I
see it already mentioned on https://wiki.centos.org/SpecialInterestGroup
among Future SIGs. Primary reason for the SIG existence will be to
improve the state of High performance computing related packages on
CentOS and similar distributions, with special focus on stability of
builds, CentOS (and similar distribution) related improvements for
OpenHPC project and getting new HPC packages packaged for CentOS and/or
Fedora.

Good to see an initiative to get the tools specific for HPC packaged, but I have a comment.

Under https://github.com/openhpc/ohpc/tree/obs/OpenHPC_1.3_Factory/components/io-libs I see spec files for software like netcdf or hdf5.

On a cluster one needs access to **many** versions of libraries (that includes compilers, python, mpi, etc.) and

packaging them as RPMS is not the correct model, unless the HPC system uses VM golden images or container images, and allows the users to start them on-demand.

What is usually used is a setup based on lmod/environment-modules like https://github.com/hpcugent/easybuild-easyconfigs

I would therefore prefer the OpenHPC project focuses in the first place on the tools a single version of which is installed on the operating system.

Best regards,

Marcin

Initial members would be me (ovasik@redhat.com, CentOS FAS account:

Thanks in advance for approving/sponsoring the SIG.
