This section describes the installation of three software packages
that, when installed, will provide you with a complete working
cluster. These packages differ radically. openMosix provides Linux
kernel extensions that transparently move processes among machines to
balance loads and optimize performance. While a truly remarkable
package, it is not what people typically think about when they hear
the word "cluster." OSCAR and Rocks
are collections of software packages that can be installed at once,
providing a more traditional Beowulf-style cluster. Whichever way you
decide to go, you will be up and running in short order.
