A maximum value of 240 GB of memory per node will be enforced from 2023-01-18. This will avoid potential out of memory situations, ensuring enough memory is left for the Operating System and other critical services running on those nodes.
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. 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.
