"The idea that you can build your own supercomputer using off-the-shelf components and even old PCs may seem far-fetched, but it's happening today with Linux clusters."

"A cluster is a group of computers bound together. The computers in the cluster work together, usually to solve mathematical problems or to provide support in case some computers in the cluster fail."

"In the different types of clusters, the main distinction is how tightly you couple the computers. Many operating systems support clustering, including VMS, Windows 2000, and Linux, where the interest in clustering has surged in recent months."

"Economics is a key factor leading to the popularity of Linux clustering. When scientific labs request bids for new systems, most want as many COTS (commercial off-the-shelf), systems as possible. The rationale is that commercially available and commercially supported systems will be cheaper: In the short run with the initial purchase, and in the long run with the ability to add computers to the cluster. And this rationale has proven true."
