Limit the number of running jobs in SLURM

Question

I am queuing multiple jobs in SLURM. Can I limit the number of parallel running jobs in slurm?

Thanks in advance!

Answer 1

According to the SLURM Resource Limits documentation, you can limit the total number of jobs that you can run for an association/qos with the MaxJobs parameter. As a reminder, an association is a combination of cluster, account, user name and (optional) partition name.

You should be able to do something similar to:

sacctmgr modify user  account= set MaxJobs=10

I found this presentation to be very helpful in case you have more questions.
