How do I tell my script or program how many cores or memory my slurm job has?

I want to be able to set cores, threads, and RAM in some way that I don’t have to hard-code the numbers for each job.

Slurm, our job scheduler, provides a number of environment variables that you can include in your job script to dynamically access the number of cores and amount of memory your job request.

$SLURM_CPUS_PER_TASK = --cpus-per-task
$SLURM_NTASKS = --ntasks
$SLURM_JOB_NUM_NODES = --nodes
$SLURM_MEM_PER_CPU = --mem-per-cpu
$SLURM_MEM_PER_NODE = --mem`
