Is there some way to limit the number of threads the job can have? We had
a problem like that - a user on a 48-core system that proceded, as the
final step of the job, to want half again as much memory as the system had
(256G!!!). After discussions, he limited what he submitted, so that's why
I wondered if you could control that administratively.
