1. Introduction

This document describes step by step instructions on building a Beowulf cluster. After seeing all of the documentation that was available, I felt there were enough gaps and omissions that my own document, which I believe accurately describes how to build a Beowulf cluster, would be beneficial.

I first saw Thomas Sterling's article in Scientific American, and immediately got the book, because its title was "How to Build a Beowulf". No doubt, it was a valuable reference, but it does not walk you through instructions on exactly what to do.

What follows is a description of what I got to work. It is only one example - my example. You may choose a different message passing interface; you may choose a different Linux distribution. You may also spend as much time as I did researching and experimenting, and learn on your own.
