This is a lulu-based print version of the famous (or infamous) book that has delighted generations of newbie cluster computer geeks for oh, six or seven years now. If are interested in cluster computing, but don't really know how it works or how to go about getting started, this is a good book for you. If you are an expert, you probably know a lot of it but still may find it funny and/or useful in places. Either way, it is available for free if you really can't afford to buy it, but by buying it you help me to write more and keep it up to date.
