This page documents the known issues for migrating jobs from Torque to Slurm.
Please be aware that $PBS_NODEFILE is a file while $SLURM_JOB_NODELIST is a string variable.
The analog on Slurm to cat $PBS_NODEFILE is srun hostname | sort -n
Environment variables do not work in a slurm directive inside a job script.
There are different ways to submit interactive jobs.
qsubqsub command is patched locally to handle the interactive jobs. So mostly you can use the qsub command as before:
| Use | Torque/Moab Command | Slurm Equivalent |
|---|---|---|
| Submit batch job | qsub <jobscript> |
sbatch <jobscript> |
| Submit interactive job | qsub -I [options] |

Slurm, which stands for Simple Linux Utility for Resource Management, is a widely used open-source HPC resource management and scheduling system that originated at Lawrence Livermore National Laboratory.
It is decided that OSC will be implementing Slurm for job scheduling and resource management, to replace the Torque resource manager and Moab scheduling system that it currently uses, over the course of 2020.
