OpenHPC: Beyond the Install Guide

Description Materials for the "OpenHPC: Beyond the Install Guide" half-day tutorial, first offered at PEARC24. The goal of this repository is to let instructors or self-learners to construct one or more OpenHPC 3.x virtual environments, for those environments to be as close as possible to the defaults from the OpenHPC installation guide, and to then use those environments to demonstrate several topics beyond the basic installation guide.

Topics include:

1. Building a login node that's practically identical to a compute node (except for where it needs to be different)
2. Adding more security to the SMS and login node
3. Using node-local storage for the OS and/or scratch
4. De-coupling the SMS and the compute nodes (e.g., independent kernel versions)
5. GPU driver installation (simulated/recorded, not live)
6. Easier management of node differences (GPU or not, diskless/single-disk/multi-disk, Infiniband or not, etc.)
7. Slurm configuration to match some common policy goals (fair share, resource limits, etc.)
