II know I'm a few weeks late with this response. I actually looked into
this 4-6 weeks ago. According to the Slurm documenntation, an individual
job step counts as a job when evaluating job limits. Pay attention to
the note in the documenation below. From
https://slurm.schedmd.com/slurm.conf.html:
*MaxJobCount*
The maximum number of jobs Slurm can have in its active database
at one time. Set the values of *MaxJobCount* and *MinJobAge* to
ensure the slurmctld daemon does not exhaust its memory or other
resources. Once this limit is reached, requests to submit
additional jobs will fail. The default value is 10000 jobs. NOTE:
Each task of a job array counts as one job even though they will
not occupy separate job records until modified or initiated.

Hi,
We use Slurm on our cluster and set a max number of all jobs. But we
would want to implement this: N concurrent individual jobs and M
concurrent jobs in all job arrays (e.g. m job arrays with n jobs in
each and M=n*m), and M is much larger than N. I have read the Slurm
documentation, but cannot find a way to separate the individual jobs
and jobs in arrays. Does anyone know how to do that?
Thank you.
