User Impact
The primary SLURM job-control tool is SRUN, (page 17) which fills the general role of PRUN (on
former Compaq machines) or POE (on IBM computers). Your choice of run mode ("batch" or interactive)
and your allocation of resources with SRUN strongly affect your job's behavior on machines where SLURM
manages parallel jobs. SLURM works collaboratively with POE on AIX machines where SLURM has
replaced IBM's LoadLeveler. See the SCONTROL section (page 65) below, for example, for an introduction
to how this collaboration supports job checkpointing.
To monitor the status of SRUN-submitted jobs, use the SLURM utility called SQUEUE (page 46).
To monitor the status of SLURM-managed compute nodes, use the complementary tool called SINFO
(page 53). Both SQUEUE and SINFO have explanatory sections later in this manual, with usage examples.
On BlueGene/L only, SLURM provides an additional user tool called SMAP (page 63) to reveal
topographically how nodes are allocated among current jobs or partitions (because job geometry is unusually
important on BG/L).
