	ITworld.com - The supercomputer in my basement
		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.

	High-performance Computing with Beowulf Clusters (Site not responding. Last check: 2007-10-12)
		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.

	Wired News: Open Supercomputing Hits Big 1-0
		Named for the hero of the epic poem written around 1000 about a man who slays a monster, Beowulf clusters are supercomputers that are built by linking individual, commodity (off-the-shelf) computers together, using an open-source architecture -- developed in part by Becker -- that enables the machines to work together.
		At Beowulf's birthday party, old photos of early Beowulf machines were projected on a screen and conversations ranged from debates about the ubiquitous "open-source beard" -- that is, the open-source programmers' preference for facial hair -- and the sad demise of so many Linux startups during the dot-com bust.
		Becker said time has proven that there are several obvious advantages to Beowulf clusters: He believes they offer the best performance bang for the buck, as well as approachable software that enables almost anyone to build his or her own cluster.

		This is the concept behind the Beowulf parallel computing system we will describe.
		It does not matter which one you choose, since nobody will be able to connect directly to a compute node from outside this network anyway.
		As soon as the new node is done booting from the floppy, an init script, found in the sbin directory under the NFS-root tree, is run and does the whole cloning process.

	Beowulf Operating System
		The Scyld Beowulf Cluster Operating System is a complete Linux distribution designed to operate and manage your entire beowulf cluster.
		The operating system needs only to be installed on the designated "master node." As each compute node is powered up on the private network, the master node automatically installs and configures the appropriate software on the compute node.
		Scyld Beowulf has been engineered from the ground up to allow users and system administrators to make a smooth transition from a stand-alone computing environment to beowulf-class computing.

	Penguin Computing - Linux Servers & Clusters - Scyld ClusterWare HPC
		The operating environment deployed to the compute nodes is provisioned “stateless”, directly to memory.
		Because the compute nodes run a lightweight, in-memory distribution, they can be provisioned rapidly so users can flexibly add or delete nodes on demand, in seconds, making the cluster extraordinarily scalable and resilient.
		Further, as depicted in the architectural diagram above, it is possible to configure Multiple Masters, each with their own default set of compute nodes, such that the Masters coordinate in the sharing of compute node resources on demand, as in a “cluster of clusters” and can provide failover backup to each other.

	ITworld.com - Penguin Computing acquires Beowulf clustering company
		Linux server company Penguin Computing Inc. is buying Scyld Computing Corp., the privately held Beowulf cluster management software vendor led by Donald Becker, a former NASA scientist and Linux networking development pioneer who will stay on as chief technology officer.
		The Beowulf concept is that high-performance massively parallel computing systems can be built out of commodity hardware components that run a free OS such as Linux or FreeBSD, with the machines linked on a high-speed connection.
		Such systems can be built inexpensively and the Beowulf movement has grown out of the needs of scientists and researchers, who often philosophically prefer to use something other than Windows, and who need a lot of computing power but don't have much money to spend.
