SLURM Reference Manual for HP XC System Software

Job Manager accepts job requests (from SRUN (page 17) or a metabatch system like LCRM),
places them in a priority-ordered queue, and reviews that queue periodically or when
any state change might allow a new job to start. Qualifying jobs are allocated resources
and that information transfers to (SLURMD on) the relevant nodes so the job can
execute. When all nodes assigned to a job report that their work is done, the Job
Manager revises its records and reviews the pending-job queue again.
