Add to your job submission:
#SBATCH --mem X
where X is the maximum amount of memory your job will use per node, in MB. The larger your working data set, the larger this needs to be, but the smaller the number the easier it is for the scheduler to find a place to run your job. To determine an appropriate value, start relatively large (job slots on average have about 4000 MB per core, but that’s much larger than needed for most jobs) and then use sacct to look at how much your job is actually using or used:
sacct -o MaxRSS -j JOBID
where JOBID is the one you’re interested in. The number is in KB, so divide by 1024 to get a rough idea of what to use with –mem (set it to something a little larger than that, since you’re defining a hard upper limit).
