That's a reasonable point. And, to boot, the messages in Maui are
incredibly cryptic; deciphering the output from checkjob can test one's
skill. But, just for my understanding/learning, does Maui not have the
capability of limiting the number of nodes per user or the number of
processors per user? Is what I'm encountering the result of a limitation
in Maui or is it that the features are there but I just haven't done it
