Job Submission

  • Get help with the complete command options sbatch --help
  • sbatch: submit a job to the batch queue system
sbatch myjob.sh
  • srun: request an interactive node(s) and login automatically
srun -A ac_xxx -p lr5 -q lr_normal -t 1:0:0 --pty bash
  • salloc : request an interactive node(s)
salloc –A pc_xxx –p lr6 –q lr_debug –t 0:30:0

Job Monitoring

  • sinfo: check status of partitions and nodes (idle, allocated, drain, down) sinfo –r –p lr6
  • squeue: check jobs in the batch queuing system (R or PD)
squeue –u $USER
  • sacct: check job information or history
sacct -X -o 'jobid,user,partition,nodelist,stat'
  • scancel : cancel a job
scancel jobID
  • Check slurm association, such as qos, account, partition
sacctmgr show association user=UserName -p
