    If your serious about clustering and making changes to the
    source code, then why not utilize a Operating environment
    suited to the task? The latest Linux kernal supports clustering as
    do most flavors of UNIX. Why not just port the application to
    run under *nix? Why support all of the Windoze overhead?

    The writing is on the wall. Check out what MSC is doing with
    Linux (no, I don't work for them, I just run
    their NASTRAN product under Windoze). You're talking
    about some SERIOUS number crunching. You need a platform
    that's up to the task.
