Request the maximum ntasks be invoked on each node. Meant to be used with the --nodes option.
This is related to --cpus-per-task=ncpus, but does not require knowledge of the actual number of
cpus on each node. In some cases, it is more convenient to be able to request that no more than a
specific number of tasks be invoked on each node. Examples of this include submitting a hybrid
MPI/OpenMP app where only one MPI "task/rank" should be assigned to each node while allowing the
OpenMP portion to utilize all of the parallelism present in the node, or submitting a single
setup/cleanup/monitoring job to each node of a pre-existing allocation as one step in a larger job
