[slurm-users] How to look for free nodes of a certain constraint efficiently

2021-10-14 Thread Thompson, Matt (GSFC-610.1)[SCIENCE SYSTEMS AND APPLICATIONS INC]
All, I work on a cluster that uses SLURM which has various types of nodes that are are controlled via --constraint flags in sbatch. Now, I started thinking "How can I figure out how many jobs are running/pending/etc on a certain type of node?". I first thought obviously "squeue --constraint=fo

[slurm-users] Query about sbatch: Request X nodes in a range?

2021-07-14 Thread Thompson, Matt (GSFC-610.1)[SCIENCE SYSTEMS AND APPLICATIONS INC]
All, A simple user SLURM question. Recently I had a need to request a certain range of nodes on a cluster, and I found SLURM was acting against my assumption, but exactly as the man page says. Namely, I needed say, 20 nodes on a cluster on the same rack (benchmarking!), but I suspected that so

[slurm-users] Help with PMIx, Slurm, Intel MPI

All, This is probably going to be a very basic question, but I find the need to ask. Recently the cluster I use installed UCX and PMIx, which is nice. Now I'm currently trying to build a stack of Open MPI 4.0.0 with the ability to see those, but until then I thought I'd try Intel MPI based on
