Linux Clusters White Paper

Clustered computing has been around for several years. Clusters have been devised, formally or informally, from many types of systems. On one extreme, the IBM eServer zSeries, when configured in a Sysplex, represents a cluster. At the other end of the power spectrum, many organizations have assembled Intel and other...
