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-l... 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
Yes, understood, thanks for the comment. With containers being more and more popular, I think even packaging these applications and libraries makes more sense. Of course, optimizing build for the specific system would be even better, but package still gives you a way how to easily install/update/remove some application with all its dependencies.
For many versions of libs and compilers - sometimes it may make sense to create a matrix of rpms like is done in the case of openHPC initiative, sometimes probably software collections can be used to get multiple versions of library/dependency on the system in parallel.
Goal is not to solve everything - this is of course out of scope - but to improve current situation and maybe to start discussion like this - how to proceed, what is missing and what is expected to be missing (because it doesn't make sense to have it as distribution package).
Regards, Ondrej
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
