A new page has been added to the site to explain the complicated node boot process (link). The page is defiantly not yet complete, only the first few stages have been fully explained. It is hoped that this page may serve as a reference to other cluster builders.
By offering all this information for free, I am hoping to inspire a new generation of clusterers. People of the world, put down you iPad, iPhone, iMac, iPod and learn to do something useful with a computer. Stop wasting your time making photo montages, and go out a build a cluster! Only once you can solve complicated engineering and scientific problems, can you really experience the true exhilaration of life! </inspirational>
