Computing Cluster Supercomputer

Recently, scientists at universities and national labs have constructed supercomputers by linking inexpensive PCs in a computing cluster, and this concept promises to revolutionize the computing field. The NASA researchers named their cluster Beowulf and this name has been widely adopted to refer to any low-cost cluster of commercial PCs. The Linux operating system is ideal for clustered PCs. The PCs coordinate their tasks by sending messages to one another, and two popular systems for doing this that are available free on the Internet are message-passing interface (MPI) and parallel virtual machine (PVM). The Oak Ridge National Lab cluster consists of 130 PCs; one machine serves as the front-end node for the cluster and it has two Ethernet cards, one for communicating with users and one for communicating with the other PCs.

and the following sites: This project entails networking 4-10 PCs into a cluster, obtaining and installing the Linux operating system, obtaining an appropriate parallel programming algorithm for the usual master-slave arrangement, getting everything operational, and obtaining sample results. Free versions of Linux are available and Pace technical support staff, Mike Sidaras and Tom Lombardi, will supply the PCs in Room 406 of the Graduate Center.
