A beowulf cluster is formed using normal computers that are identical. These are arranged into a small local area network (LAN). There are programs that allow these computers to share processing among them.So beowulf clusters form a parallel processing unit using common personal computers.

Some important features of beowulf clusters are as follows −
Some operating systems that are used for beowulf clusters are −
This is a proprietary distributed operating system whose early versions were based on Unix systems. Now MOSIX focuses on Linux grids and clusters.
This is an open source software project. The Kerrighed project started at the The French National Institute for Research in Computer Science and Control but was later adopted by the company We Cluster, Inc.
This is a Linux distribution and uses the openMosix kernel. ClusterKnoppix is quite useful as it reduces the work required for clustered computing.
