: You can get information on MPI implementations at
: http://www.mcs.anl.gov/mpi .  MPICH, among other implementations, 
: runs under FreeBSD.

Furthermore, MPICH (among others) supports the sort of "simulation" Axel
was originally asking about.  For example, if you have a single computer
in your hostfile (replicated many times) and say

	mpirun -np 4 foo

then foo is multitasked instead of running in parallel.
