PBS just distributes jobs over a bunch of machines, according to default
or specified criteria. What you want is MPI or PVM, which aids in the
distribution of the work. If you wanted to run 500 jobs on a bunch of
machines, then PBS is what you want. Apart from clever compilers, there
aren't really any good ways to magically distribute a single cpu job
onto a cluster.
