| + | ===== Basics ====== | ||
| + | |||
| + | * Submit batch jobs | ||
| + | |||
| + | <code> | ||
| + | $ sbatch script.job | ||
| + | </code> | ||
| + | |||
| + | * Cancel jobs | ||
| + | |||
| + | <code> | ||
| + | $ scancel jobid | ||
| + | </code> | ||
| + | |||
| + | * View the queue | ||
| + | |||
| + | <code> | ||
| + | $ squeue | ||
| + | </code> | ||
| + | |||
| + | See below for example job scripts. | ||
| + | |||
| + | ===== Random Tips & Tricks ===== | ||
| + | |||
| + | * Attach to a running job [[https://computing.llnl.gov/linux/slurm/sattach.html]] | ||
| + | |||
| + | <code> | ||
| + | $ sattach jobid.jobstep | ||
| + | </code> | ||
| + | |||
| + | * We can hold a job by postponing it's start time [[https://computing.llnl.gov/linux/slurm/faq.html#hold]] | ||
| + | |||
| + | <code> | ||
| + | $ scontrol update JobId=1234 StartTime=now+30days | ||
| + | ... later ... | ||
| + | $ scontrol update JobId=1234 StartTime=now | ||
| + | </code> | ||
| + | |||
| + | * If you want squeue to look like at CSCS, add the following to your .bashrc | ||
| + | |||
| + | <file> | ||
| + | alias squeue="squeue --format='%.12i %.8u %.9P %.32j %.12B %.2t %.12r %.14M %.14L %.6D %.10Q'" | ||
