Question

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

Thanks in advance!

If you are not the administrator, your can hold some jobs if you do not want them all to start at the same time, with scontrol hold <JOBID>, and you can delay the submission of some jobs with sbatch --begin=YYYY-MM-DD. Also, if it is a job array, you can limit the number of jobs in the array that are concurrently running with for instance --array=1:100%25 to have 100 jobs in the array but only 25 of them running.
