WebbCPUs per node, or ‘ntasks’ as slurm identifies them, determine how many CPU cores your job will use to run. Most nodes on the engaging cluster, including the public partitions such as engaging_default, have between 16 and 20 CPUs. You can view the amount of CPUs per specific nodes with the command: scontrol show node node [number] WebbDetecting inefficient jobs¶. You can filter for a slurm job ID, account name or user name with the search bar in the upper left corner. For single- or multinode jobs the AvgNodeLoad is an important indicator if your jobs runs efficiently, at least with respect to CPU usage.
