> It's a 32-bit dual xeon system - no opteron, unfortunately.  So I guess configuring the MPI/Scalapack ... or buying opterons is the only thing we can do.

As I said before: The mpi version requires twice as much memory. So if
you just parallelize on a dual PC system, you won't gain anything in terms
of memory.
