Good to see an initiative to get the tools specific for HPC packaged, but I
have a comment.
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
What is usually used is a setup based on lmod/environment-modules like

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.
