On Ultrix versions up through 3.1, the parallel processing isn't visible
through normal means.  You can see it with iostat and you can certainly
feel the difference if you run a GNU Make in parallel mode :-).  The
multiprocessor support gets a lot better in 4.0, but until then all it's
really doing is allocating a processor at schedule-time -- EACH schedule
time.  Your job doesn't get "allocated" to a processor.  Even in 4.0 it
won't be "allocated", it's a many-processors-to-many-jobs mapping that
takes place continuously.
