However, I've stumbled across what appears to be an inconsistent passage:<br /> <br /> * The parameter &lt;tt&gt;-j $SLURM_TASKS_PER_NODE&lt;/tt&gt; tells &lt;tt&gt;parallel&lt;/tt&gt; to run 40 subjobs simultaneously on each of the nodes (note: do not use the similarly named variable $SLURM_TASKS_PER_NODE as its format is incompatible with GNU parallel).<br /> <br /> The parallel manual specifies that the &lt;tt&gt;-j&lt;/tt&gt; option controls the number of jobslots to use on each machine. Thus, I think the correct option is &lt;tt&gt;-j $SLURM_NTASKS_PER_NODE&lt;/tt&gt; and not &lt;tt&gt;-j $NCORES&lt;/tt&gt; (used in the code example) or &lt;tt&gt;-j $SLURM_TASKS_PER_NODE&lt;/tt&gt; (used in the passage). The parenthetical note seems to be correct but is currently difficult to comprehend because of this typo.</div>
