My head hurts. Doing a deep-dive into containerization/VM with #Jenkins. So many options. I think I'll give #LXD a shot. But frankly, since my #OpenMPI program is already containerized via #Apptainer, I'll just go ahead and build on the (fairly powerful) Jenkins host for now, just to get the pipeline built as a proof of concept.
Time for an adult beverage.
Finishing some runtime system work; decided to try a #deskpi #super6c cluster board.
An ITX form factor beowulf cluster is amazing.
#slurm & #nfs worked out of apt.
#ucx, #openmpi, #openshmem, #openpmix, #gasnet, & #hpx needed custom compilation.

@kylewritescode Good morning Kyle.
I already had a productive morning. I finally figured out how to let my hybrid #Apptainer #OpenMPI container for our NASA code talk to #UKY's #HPC cluster’s InfiniBand backend. Now the code scales beautifully. Next up, getting it to run on our collaborators’ cluster at #UMN.
I think I’ll have my coffee now.
For @centos #Hyperscale users, we now have a fixed #pmux for CVE-2023-41915 and an upgraded #openmpi and rebuilt #slurm to go with it
