This tutorial will show how to install a 16 node cluster, which supports perl for parallel processing, step by step. 
along with life demonstration!

From a hardware component and raw processing power perspective, commodity clusters are phenomenal price/performance compute engines. However, if a scalable ``cluster'' management strategy is not adopted, the favorable economics of clusters are offset by the additional on-going personnel costs involved to ``care and feed'' for the machine. The complexity of cluster management (e.g., determining if all nodes have a consistent set of software) often overwhelms part-time cluster administrators, who are usually domain application scientists. When this occurs, machine state is forced to either of two extremes: the cluster is not stable due to configuration problems, or software becomes stale, security holes abound, and known software bugs remain unpatched.
