I have recently installed PVM 3.3.11 on our new Sun UltraSparc ES3000. 
This machine has 2 processors and this is my first experience with a
multiprocessor machine.  I have used PVM for years on SP machines.  How
can I make sure when I run PVM on this machine that it will use both
processors?  From what I read on the PVM web page and in the README files,
I don't think I need to do anything special.  However, the timing when I
run my code using PVM is only slightly faster than when I run it without
using PVM.  When no on else is using the machine it should be nearly twice
as fast with PVM, so I don't think I am using both processors.

Any suggestions?  I use PVM in its most basic configuration and I was not
the one who adapted my code for use with PVM, so I probably can't do any
very sophisticated analysis of this problem.

Thanks,

Tara
