| * ''[...]$ scontrol'' is used to view SLURM configuration including: job, job step, node, partition, reservation, and overall system configuration. Without a command entered on the execute line, scontrol operates in an interactive mode and prompt for input. With a command entered on the execute line, scontrol executes that command and terminates. | * ''[...]$ scontrol'' is used to view SLURM configuration including: job, job step, node, partition, reservation, and overall system configuration.
