SLURM-Environment Variables

Environment variables

Any environment variables that you have set with the sbatch command will be passed to your job. For this reason, if your program needs certain environment variables set to function properly, it is best to put them in your job script. This also makes it easier to reproduce your job results later, if necessary.

In addition to setting environment variables yourself, Slurm provides some environment variables of its own that you can use in your job scripts. Information on some of the common slurm environment variables is listed in the chart below. For additional information, see the man page for sbatch.

Environmental Variable Definition
$SLURM_JOB_ID ID of job allocation
$SLURM_SUBMIT_DIR Directory job where was submitted
$SLURM_JOB_NODELIST File containing allocated hostnames
$SLURM_NTASKS Total number of cores for job

NOTE: Environment variables override any options set in a batch script. Command-line options override any previously set environment variables.
