I don't think so, but I don't have resources_max.ncpus either (I suggest
you unset it, too). It could also be (more likely) that you have another
resources_default.ncpus defined at the server level (qmgr list server),
not at the queue level.

Yes, if they want 4 CPUs from the same machine (usually they do). If they
don't care about which machines the 4 CPUs come from, that would be
nodes=4 (strange as it may sound). It could be that some configuration
parameters need to be set that affect the interpretation of nodes=4 to
make it work (give it a try and see whether you get 4 CPUs or 4 machines
with 1 CPU each).
