Script Variables

Info Slurm Notes
Version Can extract from sbatch --version
Job name $SLURM_JOB_NAME  
Submit directory $SLURM_SUBMIT_DIR Slurm jobs starts from the submit directory by default
Node list $SLURM_JOB_NODELIST The Slurm variable has a different format to the PBS one.
To get a list of nodes use:
scontrol show hostnames $SLURM_JOB_NODELIST
Job array index $SLURM_ARRAY_TASK_ID  
Number of nodes allocated $SLURM_JOB_NUM_NODES
Number of processes $SLURM_NTASKS  
Number of processes per node $SLURM_TASKS_PER_NODE  
Requested tasks per node $SLURM_NTASKS_PER_NODE  
Requested CPUs per task $SLURM_CPUS_PER_TASK  
Scheduling priority $SLURM_PRIO_PROCESS  
Job user $SLURM_JOB_USER  
Hostname $HOSTNAME == $SLURM_SUBMIT_HOST Unless a shell is invoked on an allocated resource, the $HOSTNAME variable is propagated (copied) from the submit machine environment to all allocated nodes.
