Converting from PBS to Slurm
Slurm’s commands and scheduler directives can be mapped to and from PBS/Torque commands and scheduler directives. To convert any PBS/Torque scripts and/or workflows to Slurm, the commands and scheduler directives should be swapped out and reconfigured. See the table below for the mapping of some common commands and scheduler directives:
| Action | PBS/Torque Command | Slurm Command |
|---|---|---|
| Submit a batch job | qsub |
sbatch |
| Request an interactive job | qsub -I |
salloc |
| Cancel a job | qdel |
scancel |
| Check job status | qstat |
squeue |
| Check job status for specific user | qstat -u <user> |
squeue -u <user> |
| Hold a job | qhold |
scontrol hold |
| Release a job | qrls |
scontrol release |
| Resource Request | PBS/Torque Directive | Slurm Directive |
|---|---|---|
| Directive designator | #PBS |
#SBATCH |
| Number of nodes | -l nodes |
-N or --nodes |
| Number of CPUs | -l ppn |
-n or --ntasks |
| Amount of memory | -l mem |
--mem or --mem-per-cpu |
| Walltime | -l walltime |
-t or --time |
| Compute account | -A |
-A or --account |
