Webb1 juni 2024 · In Slurm the number of tasks is essentially the number of parallel programs you can start in your allocation. By default, each task can access one CPU (which can be core or thread, depending on config), which can be modified with --cpus-per-task=#.. This in itself does not tell you anything about the number of nodes you will get.
