    Yes.

    It's a fairly "standard" way to setup a cluster. If your question is
    more "How do I do this?", then you'll need to see what Google turns up
    that is close to what you have in mind or need.

    Haven't had the chance for a hands-on, build-it-myself experience yet,
    but have been trying to follow along. A good series (actually two, I
    believe) is available in Linux Magazine for a good one-stop start.
    Try this in a Google Web search:
    cluster site:www.linux-mag.com
    or go to Linux Magazine and enter cluster in their search box (same
    results).

    Your computational needs will dictate how to set up the slaves. This
    article covers some alternatives:
    http://www.linux-mag.com/cgi-bin/printer.pl?issue=2002-02&article=extreme

    Anyway, if there is anything I've learned so far, it is that no two
    clusters are alike -- not in the "how-to" details at least.
    Developing some "feel" up front might save you some headaches.

    Google "beowulf cluster linux" and comb through what seems useful for
    a start. As you get more familiar with your needs and terminology
    related thereto, add terms to the search to narrow your focus. Of
    course, it's obligatory to start with:
    http://www.beowulf.org/
    but you may need to check out:
    http://linux-ha.org/
    or
    http://www.linuxvirtualserver.org/

    For "higher end" solutions you can start with this Google search:
    linux cluster ibm grid

    If your nodes are geared to computational services though, beowulf
    will be your cornerstone for initial searching.
