  Computer cluster
A computer cluster is a group of connected computers to work together as a parallel computer.
One of the more popular implementations is a cluster with nodes running Linux as the OS, and Beowulf software (both free software) to implement the parallelism.
Clusters were originally developed by DEC in the 1980s.

 Computer cluster - Wikipedia, the free encyclopedia
Such a cluster of computers is sometimes referred to as a server farm.
Grid computing or grid clusters are a technology closely related to cluster computing.
The central concept of a Beowulf cluster is the use of commercial off-the-shelf computers to produce a cost-effective alternative to a traditional supercomputer.

 Computer cluster and clustering
The clusters associated with a file are kept track of in the hard disk's file allocation table (FAT).
Since a cluster is a logical rather than a physical unit (it's not built into the hard disk itself), the size of a cluster can be varied.
The tradeoff in cluster size is that even the smallest file (and even a directory itself) takes up the entire cluster.

 Cluster computer
And for computing jobs that can be broken into smaller pieces -- like the graphics program running on the monitor beside Kressler -- the result is high-speed computing at very low cost.
Using a few old computers donated by the Mitre Corp., along with castoffs from Cornell loading docks, the two students have assembled a "cluster computer" in which the whole is much faster than the sum of its parts.
But a positive side effect of cluster computing is that, since individual processors don't have to be all that fast, they don't have to be all that expensive.

 Computer cluster   (Site not responding. Last check: 2007-10-10)
A computer cluster is a group of computers that work together closely so that in many respects it can be viewed as though it were a single computer.
Clusters are commonly (but not always) connected through fast local area networks.
Clusters are usually deployed to improve speed and/or reliability over that provided by a single computer, while typically being much more cost-effective than single computers of comparable speed or reliability.

 NGS - What is a Computer Cluster?
A computer cluster is a group of closely ‘networked’ computers that work together as a single computer.
Some clusters aim to provide zero downtime via redundancy, some aim to provide high availability by load balancing tasks across the cluster and others aim to provide high performance computation via parallelism.
The NGS core clusters are at times high performance clusters and other times load balancing clusters, it all depends on the type of jobs that are being processed.

For file I/O, the computational nodes mount a partition on the controlling node's hard drive by means of a network file system mount point.
The computational nodes have 256 MB RAM, each and boot from 340 MB IBM microdrives by means of compact flash to IDE adapters.
No official benchmarks have been run, but for simple computational tasks the mini cluster appears to be faster than four 2.4 GHz pentium 4 mcahines used in parallel, at a fraction of the cost and power use.

 News Release - Sandia creates cluster computer   (Site not responding. Last check: 2007-10-10)
A cluster computer normally combines multiple commodity desktop-sized personal computers to work in parallel on problems too large for a single computer.
This “breadbox” computer is also made of commodity computer parts, but the parts are small, embedded systems normally intended for use in cars, cell phones and watches (where they are intended to run on batteries), rather than desktop computer components.
Although the four CPUs don’t offer the power and speed of a larger cluster, they will still run software created for cluster computing, so specialists can demonstrate their code at a remote location much like other presenters use laptop computers on the road to present their wares.
