Matt pointed out that --ntasks impacts the output of nproc on our system, and this led to a discussion about when --ntasks might impact downstream processing. As far as we can tell, applications are free to ignore the "advice" given by --ntasks to downstream processes, however, --ntasks has implications for how srun is used to manage tasks.
