		Beowulf is an approach to building a supercomputer by means of clustering commodity off-the-shelf (COTS) computers that are interconnected with a local area network technology like Ethernet and running programs optimized for parallel processing.
		Beowulf is loosely coupled and is a distributed memory environment that runs message passing parallel programs which do not assume a shared address space across processors.
		Incidentally, Beowulf is the name of the legendary hero who slayed the monster Grendel and became the king of the Geats in an anonymous Old English epic poem that is believed to have been composed in the early eighth century.

	Scyld Delivers Out Of The Box Beowulf Clustering.
		Beowulf cluster systems connect a series of computers together, using a modified version of Linux, to form a parallel processing supercomputer.
		The Scyld Beowulf Operating System improves upon traditional Beowulf clusters as all operations performed on the linked cluster nodes are initiated and administered through a single master node.
		About Beowulf Beowulf, and Beowulf clustering are terms that describe a technique of connecting commodity computers together using a modified version of Linux to create a High Performance Computer.

	High-performance Computing with Beowulf Clusters
		Beowulf is used today as a metaphor for a new strategy in high-performance computing that exploits mass-market technologies to overcome the oppressive costs in time and money of supercomputing, thus freeing people to devote themselves to their respective disciplines.
		Ironically, building a Beowulf cluster is so much fun that scientists and researchers eagerly roll up their sleeves to undertake the many tedious tasks involved—at least for the first time they build one.
		The goal in building a Beowulf cluster was to create a cost-effective parallel computing system from mass-market commodity, off-the-shelf components to satisfy specific computational requirements in the earth and space sciences community.

		A HPC Cluster, also known as a Beowulf Cluster is simply a group of server, connected via a network, that utilize message passing software to parse a problem into many smaller parts and distribute those parts to each server.
		To better understand what a Beowulf Cluster is and is not, it is easiest to compare it to the computer architecture it most closely resembles.
		A Beowulf Cluster is not a true shared memory computer because the memory on each server, or node as it is commonly referred, is available only to the processors on that server.

		Beowulf clusters are high-performance computers built from off-the-shelf commodity components.

		"Beowulf was a [super] computer with one of the first Linux-based architectures." For example, Regetin points out, Beowulf-class computers use a lot of different methods to interconnect their processors.
		Basically, a Beowulf system consists of one or more master nodes, which are fully configured systems with I/O devices, and a lot of slave nodes, which are usually just motherboards or PCs with no display, no keyboard, and minimal or no hard disk storage.
		Beowulf being Linux, and Linux being Linux, there are a lot of sources of information and advice to help you set up a Beowulf system.

	Beowulf Cluster at Linux 99
		The Beowulf project is a NASA initiative sponsored by the HPCC program to explore the potential of Pile-of-PCs and to develop the necessary methodologies to apply these low cost system configurations to NASA computational requirements in the Earth and Space sciences.
		Clustering is a popular strategy for implementing parallel processing applications because it enables companies to leverage the investment already made in PCs and workstations.
		Beowulf nodes can be thought of as a CPU + memory package which can be plugged into the cluster, just like a CPU or memory module can be plugged into a motherboard.

	Beowulf clusters: e pluribus unum
		This is the Beowulf strategy: divide programs into many parts that are executed by many CPUs that run under as many copies of Linux, all of which transfer their data and instructions via Ethernet.
		For example, Boeing received a Beowulf cluster from Linux NetworX to design the Delta IV rocket, which is itself used to launch satellites.
		The Beowulf strategy produces the Beowulf effect, that is, the use of more processors to compute in less time what it would take fewer processors to compute in more time.

	Beowulf Gigaflop/s Workstation Project
		In a Cluster Computer, the nodes lose their individuality, and the operating system parameters are tuned to make a single parallel program run efficiently across the entire cluster.
		The Beowulf project was presented (by Donald Becker) as a keynote session at IEEE Aerospace '97 and a CESDIS/JPL/Caltech collaboration produced the "How to build a Beowulf tutorial" that has been given twice and is scheduled to be given twice more this fall.
		Each node in the cluster still runs its own copy of the kernel, as does a node in a network of workstations; however, that image is obtained from a master node at boot time, unlike a network of workstations.

	Computer cluster - Wikipedia, the free encyclopedia
		Clusters are usually deployed to improve performance and/or availability over that provided by a single computer, while typically being much more cost-effective than single computers of comparable speed or availability.
		High-availability clusters (a.k.a Failover clusters) are implemented primarily for the purpose of improving the availability of services which the cluster provides.
		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.

	Beowulf HOWTO
		Beowulf architecture scales well, it is easy to construct and you only pay for the hardware as most of the software is free.
		Beowulf nodes can be thought of as a CPU + memory package which can be plugged in to the cluster, just like a CPU or memory module can be plugged into a motherboard.
		Because there is no need for client nodes to access machines outside the cluster, nor for machines outside the cluster to access client nodes directly, it is a common practice for the client nodes to use private IP addresses like the 10.0.0.0/8 or 192.168.0.0/16 address ranges (RFC 1918 http://www.alternic.net/rfcs/1900/rfc1918.txt.html).

		As we all know by now, the original concept for Beowulf clusters was conceived by Donald Becker while he was at NASA Goddard in 1994.
		Some common problems plagued the first-generation Beowulf clusters, largely because the system management tools to control the new clusters did not scale well because they were more platform- or operating-specific than the parallel programming software.

	Clusters
		The interest for clusters can be seen for instance from the active IEEE Task Force on Cluster Computing (TFCC) which reviews the current status of cluster computing on a regular basis [43].
		As the cluster scene becomes relatively mature and an attractive market, large HPC vendors as well as many start-up companies have entered the field and offer more or less ready out-of-the-box cluster solutions for those groups that do not want to build their cluster from scratch.
		By contrast, Beowulf clusters are mostly operated through the Linux operating system (a small minority using Microsoft Windows) where these operating systems either miss the tools or these tools are relatively immature to use a cluster well for capacity computing.
