Talk:Running Serial Jobs on Niagara

Inconsistency

Hello, thanks for the work you've done preparing these help files as they are quite useful. However, I've stumbled across what appears to be an inconsistent passage:

• The parameter -j $SLURM_TASKS_PER_NODE tells parallel 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).

The parallel manual specifies that the -j option controls the number of jobslots to use on each machine. Thus, I think the correct option is -j $SLURM_NTASKS_PER_NODE and not -j $NCORES (used in the code example) or -j $SLURM_TASKS_PER_NODE (used in the passage). The parenthetical note seems to be correct but is currently difficult to comprehend because of this typo.
