Example of a Beowulf Node

The majority of Beowulfs (over five generations of systems in the past seven years) have employed microprocessors from Intel or AMD. This is because they have been among the least expensive systems to build, the system architectures are open providing a wealth of component choices, and the Linux operating system was first available on them. While not the fastest processors in peak performance, their overall capability has been good, and their price performance ratios are excellent. The most...

Hardware System Structure

The most visible and discussed aspects of cluster computing systems are their physical components and organization. These deliver the raw capabilities of the system, take up considerable room on the machine room floor, and yield their excellent price performance. The two principal subsystems of a Beowulf cluster are its constituent compute nodes and its interconnection network that integrates the nodes into a single system. These are discussed briefly below. The compute or processing nodes...
