SLURM/JobStatus
Job Status
SLURM offers a variety of tools to check the status of your jobs before, during, and after execution. When you first submit your job, SLURM should give you a job ID which represents the resources allocated to your job. Individual calls to srun will spawn job steps which can also be queried individually.
squeue
The squeue command shows job status in the queue. If your job has not yet started, you can ask for an estimated start time with squeue --start
tgray26@opensub00:squeue
JOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON)
162 test2 helloWor tgray26 R 0:03 2 openlab[00-01]
If you want to see the status of individual job steps you can use squeue -s
tgray26@opensub00:squeue -s
STEPID NAME PARTITION USER TIME NODELIST
162.0 sleep test2 tgray26 0:05 openlab00
162.1 sleep test2 tgray26 0:05 openlab01
sstat
The sstat command shows metrics from currently running job steps. If you don't specify a job step, the lowest job step is displayed.
sstat --format JobID,NTasks,nodelist,MaxRSS,MaxVMSize,AveRSS,AveVMSize <$JOBID>.<$JOBSTEP>
tgray26@opensub00: sstat --format JobID,NTasks,nodelist,MaxRSS,MaxVMSize,AveRSS,AveVMSize 171
JobID NTasks Nodelist MaxRSS MaxVMSize AveRSS AveVMSize
------------ -------- -------------------- ---------- ---------- ---------- ----------
171.0 1 openlab00 0 186060K 0 107900K
tgray26@opensub00: sstat --format JobID,NTasks,nodelist,MaxRSS,MaxVMSize,AveRSS,AveVMSize 171.1
JobID NTasks Nodelist MaxRSS MaxVMSize AveRSS AveVMSize
------------ -------- -------------------- ---------- ---------- ---------- ----------
171.1 1 openlab01 0 186060K 0 107900K
Note that if you do not have any jobsteps, sstat will not return an error.
tgray26@opensub00: sstat --format JobID,NTasks,nodelist,MaxRSS,MaxVMSize,AveRSS,AveVMSize 172
JobID NTasks Nodelist MaxRSS MaxVMSize AveRSS AveVMSize
------------ -------- -------------------- ---------- ---------- ---------- ----------
If you do not run any srun commands, you will not create any job steps and metrics will not be available for your job. Your batch scripts should follow this format:
#!/bin/bash #SBATCH ... #SBATCH ... # set environment up module load ... # launch job steps srun <command to run> # that would be step 1 srun <command to run> # that would be step 2
sacct
The sacct command shows metrics from past jobs.
tgray26@opensub00:sacct
JobID JobName Partition Account AllocCPUS State ExitCode
------------ ---------- ---------- ---------- ---------- ---------- --------
162 helloWorld test2 staff 2 COMPLETED 0:0
162.batch batch staff 1 COMPLETED 0:0
162.0 sleep staff 1 COMPLETED 0:0

163 helloWorld test2 staff 2 COMPLETED 0:0
163.batch batch staff 1 COMPLETED 0:0
163.0 sleep staff 1 COMPLETED 0:0
To check one specific job, you can run something like the following (if you omit .<$JOBSTEP>, all jobsteps will be shown):
sacct --format JobID,jobname,NTasks,nodelist,MaxRSS,MaxVMSize,AveRSS,AveVMSize,Elapsed -j <$JOBID>.<$JOBSTEP>
tgray26@opensub00:sacct --format JobID,jobname,NTasks,nodelist,MaxRSS,MaxVMSize,AveRSS,AveVMSize,Elapsed -j 171
JobID JobName NTasks NodeList MaxRSS MaxVMSize AveRSS AveVMSize Elapsed
