Any parallel jobs explicitly asking for more than 240 GB with the #SBATCH --mem directive or the --mem command line option will fail at submission time with the message:
| No Format |
|---|
sbatch: error: Memory specification can not be satisfied
sbatch: error: Batch job submission failed: Requested node configuration is not available |
. Since parallel jobs are assigned nodes exclusively, and therefore can use all the memory available in the nodes, it is usually easier to avoid defining that option all together in parallel jobs.
