Beowulf

Also called Beowulf computing or Beowulf cluster computing, it is a High Performance Computing Cluster (HPCC) that consists of clustering computer systems on a high speed network running open source operating systems, like Linux or FreeBSD and also using Beowulf software to function as a single massive parallel computer. Beowulf clusters are most commonly used for computational intensive tasks including digital media rendering, seismic analysis, or computational chemistry.
