A quick & easy way to see what your options might be for Slurm environment variables is to try a job like this:
$ srun --nodes 2 --ntasks-per-node 6 --pty env | grep SLURM
Or, perhaps, use the “env | grep SLURM” in your batch script.

If you are using mpi, it should be aware automatically if everything was compiled with support (eg mpirun).
If you are looking to just get the total tasks, $SLURM_NTASKS is probably what you are looking for

A genetic program uses -num_threads in command line for parallel run. I use the following directives in slurm batch file
for 12 processes and 24GB of memory. Is there any slurm variable that counts all threads from the directives? So, I can use
where SLURM_COUNT is 12. Any idea?
