Updated list of Slurm variables.

Slurm Job Environment Variables
Slurm Variable Name	Description	Example values
$SLURM_CPUS_ON_NODE	Number of cores/node	8,3
$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.	8,3
$SLURM_JOB_ID	Job ID	5741192
$SLURM_JOBID	Deprecated. Same as SLURM_JOB_ID
$SLURM_JOB_NAME	Job Name	myjob
$SLURM_JOB_NODELIST	Nodes assigned to job	compute-b24-[1-3,5-9],compute-b25-[1,4,8]
$SLURM_JOB_NUM_NODES	Number of nodes allocated to job	2
$SLURM_LOCALID	Index to core running on within node	4
$SLURM_NODEID	Index to node running on relative to nodes assigned to job	0
$SLURM_NNODES	Deprecated. Same as SLURM_JOB_NUM_NODES	4
$SLURM_NODELIST	Deprecated. Same as SLURM_JOB_NODELIST	compute-b24-[1-3,5-9],compute-b25-[1,4,8]
$SLURM_NTASKS	Total number of cores for job???	11
$SLURM_PROCID	Index of task relative to job	0
$SLURM_SUBMIT_DIR	Submit Directory	/lustre/payerle/work
$SLURM_SUBMIT_HOST	Host submitted from	login-1.deepthought2.umd.edu
$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.
