'''"-j $TASKS_PER_NODE"''' determines the number of concurrently running tasks per node, which is defined by '''TASKS_PER_NODE=`echo $SLURM_NTASKS / $SLURM_NNODES | bc`'''. '''scontrol show hostname $SLURM_NODELIST > machinefile''' makes a list of nodes and send it to GNU parallel by "--slf $MACHINEFILE".
