<p>I ask if you are specifying it, because if not, slurm will assume
a job will use all the memory available.</p>
<p>So without specifying, your big job gets allocated 100% of the
memory so nothing could be sent to the node. Same if you don't
specify for the little jobs. It would want 100%, but if anything
is running there, 100% is not available as far as slurm is
concerned.</p>

<p>Can't run a small job if there isn't enough memory
available for it.</p>
