For example, when a long list of OpenMP tasks are executed as a single job submitted with --nodes=N, --ntasks-per-node=5 and --cpus-per-task=8, the following command will take into account all processes to be started on all reserved nodes and the number of OpenMP threads per process:
[name@server ~]$ parallel --jobs $SLURM_NTASKS_PER_NODE --sshloginfile ./node_list_${SLURM_JOB_ID} --workdir $PWD --env OMP_NUM_THREADS=$SLURM_CPUS_PER_TASK --sshdelay 30 ./my_program
In this case, up to 5*N OpenMP processes are running simultaneously with a CPU usage of up to 800% each.
