I must mention to the present debate that I have emulated a Linux cluster on my
350 MHz Linux Station using MPI library (Message Passing Interface) with MPICH.
Instead of running a program on several machines, the trick is to change the mpi
shell to run several "bash" in parallel. Of course this is not real parallelism
but it is a good way to test real parallel codes. I managed to run up to 16
parallel processes (beyond you may have troubles).
