Although I haven't tried any other MPI implementation, MPICH (from Argonne)
works nicely.  I've used it on networks of IBM RS/6000s and HP workstations
(and on an IBM SP-2).  It's very easy to install (although it's rather
large), especially on a homogeneous network (all the executables are of the
same format) because then you can just copy things over.

The only extra thing you have to do is create a host file (in the util/
directory) which lists the hosts that you would want to spawn to when using
mpirun.  One other thing: when I first installed MPICH I had no idea what
"device" I should use... I thought I'd have to install another message-passing
system..  In fact, you just use the p4 device, which comes with the MPICH
package.
