I'll take this one. I think we can integrate openHPC as a separate playbook.

Let's provide some documentation mentioning that it currently provides good MPI performance for OFED-based networks, but does not yet have UCX-based support for RoCE/IB with Mellanox. This will be fixed with openHPC 2.0 (openhpc/ohpc#1203).

OHPC 2.0 repos are now available on OBS (http://obs.openhpc.community:82/OpenHPC:/2.0:/Factory/).

It appears that all RPMs are built for CentOS8. @j0hnL should we consider a base OS version bump?

[lwilson]

The .repo file is at http://obs.openhpc.community:82/OpenHPC:/2.0:/Factory/CentOS_8/OpenHPC:2.0:Factory.repo

[OpenHPC_2.0_Factory]
name=Rolling development build (CentOS_8)
type=rpm-md

OpenHPC 2.0 is now officially released. The repo is available at: http://repos.openhpc.community/OpenHPC/2/CentOS_8/

rather than integrating the repos we should look into using the OHPC container: https://github.com/openhpc/ohpc/tree/2.x/containers

[lwilson]

Completely agree @j0hnL. It also appears that we can take Slurm directly from epel-release: https://centos.pkgs.org/8/epel-x86_64/slurm-20.11.5-1.el8.x86_64.rpm.html

Since this is the case, I would suggest we use the epel-release version of Slurm, and then use Singularity (#300) to deploy NGC, oneContainer, OpenHPC containers for user applications.

@j0hnL I'm closing this ticket. Since we are deploying the OpenHPC application environment via container, I think we can consider this task complete.
