<p>... to complete my thought, I don't think what you want to do is
possible. If M is the number of job steps, and N is total jobs, M
cannot be greater than N. <br>

<p>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 <a class="moz-txt-link-freetext"

<dl compact="compact">
<dt><b>MaxJobCount</b></dt>
<dd> The maximum number of jobs Slurm can have in its active
database at one time. Set the values of <b>MaxJobCount</b>
and <b>MinJobAge</b> 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.</dd>

<p class="MsoNormal"><span
style="font-size:11.0pt;color:black">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?</span><span
