Hello,
Did you try adding something like that to slurm.conf?
NodeName=cnode001 CPUs=48
Cheers,
Colas

I should start out by saying that I am extremely new to anything HPC.
Our end users purchased a 20 node cluster which a vendor set up for us
with Bright/Slurm.
After our vendor said everything was complete and we started migrating
our users workflow to the new cluster they discovered that they can't
run more than 1 job per node at a time. We started researching
enabling consumable resources which I believe we've done so however
we're getting the same result.
I've just discovered today that both *scontrol show node* and *sinfo
-lNe* show that each of our nodes have 1 CPU. I'm guessing that's why
we can't submit more than 1 job at a time. I'm trying to determine
where is it getting this information and how can I get it to display
the correct CPU information.

I can provide other configs if you feel that it could help.
Any ideas? I would have thought that slurm would grab the CPU
information from the CPU instead of the configuration.
Thanks
Chris
