High-Performance Linux Clustering
An anonymous reader writes "High Performance Computing (HPC) has become easier, and two reasons are the adoption of open source software concepts and the introduction and refinement of clustering technology. This first of two articles discusses the types of clusters available, uses for those clusters, reasons clusters have become popular for HPC, some fundamentals of HPC, and the role of Linux in HPC."
Cluster is very easy to implement today because there is a lot of software that can configure itself and connect to cluster nodes like OpenMosix
