A solution to the problem of large scale, high cost, energy consuming super computers. It details the construction of a small foot print, cost effective, and energy efficient cluster system. The system uses Raspberry Pi computers to create a cluster that is much less expensive and significantly smaller than traditional super computers. The system does not sacrifice computing power in proportion to its size and energy consumption.
