I'm not sure how you'd explicity force each of the two processes onto different
CPUs on the Sparc20.  I have this question myself.  However, processes seem to
alternate between the two CPUs.  I don't know if this is by design, or an
accident, but I like it.  You can use "proctool" under Solaris 2.x to verify
the loads on each of the two processors, to confirm that each is running on its
own processor.

I'm still stumped about configuring this system for shared memory message
passing.  If you or any other readers have any insight, I would really
appreciate some advice.  I'm starting to think MPI (specifically mpich) won't
work in shared memory mode on a Sparc box running solaris 2.x.  Any comments?
Thanks :)
