Slurm passes configuration data to jobs via environmental variables. The following is a list of commonly used variables that are set by Slurm for each job
| Slurm Variable Name | Description |
|---|---|
| $SLURM_CPUS_ON_NODE | Number of cores/node |
| $SLURM_CPUS_PER_TASK | Number of cores per task. I.e., the value given to the -cpus-per-task or -c sbatch options. Not set unless one of those options given. |
| $SLURM_JOB_ID | Job ID |
| $SLURM_JOBID | Deprecated. Same as SLURM_JOB_ID |
| $SLURM_JOB_NAME | Job Name |
| $SLURM_JOB_NODELIST | Nodes assigned to job |
| $SLURM_JOB_NUM_NODES | Number of nodes allocated to job |
| $SLURM_LOCALID | Index to core running on within node |
| $SLURM_NODEID | Index to node running on relative to nodes assigned to job |
| $SLURM_NTASKS | Total number of cores for job |
| $SLURM_PROCID | Index of task relative to job |
| $SLURM_SUBMIT_DIR | Submit Directory |
| $SLURM_TMPDIR | Temporary directory. See also Temporary Directories. |
| $SLURM_SUBMIT_HOST | Host submitted from |
| $SLURM_TASKS_PER_NODE | This gives a comma-delimited list of integers representing the task per the node, using the same ordering as in SLURM_JOB_NODELIST. If consecutive nodes have the same task count, the integer will be followed by '(xN)', so the example value is for 2 tasks on the first three nodes and 1 task on the fourth node. |
