The Terascale Computing System was built through a joint effort by the University of Pittsburgh, Carnegie Mellon University and Westinghouse Electric at the PSC. It was developed with Compaq, using funding from the National Science Foundation.
The machine was built from 3,000 Compaq Alpha EV68 microprocessors and is housed in 750 four-processor AlphaServer systems running Tru64 Unix. The machine has 6 teraflops of processing power, 3Tbytes of memory, and high-bandwidth, low-latency interconnections.
The project began in October 2000 with the installation of a 256-processor prototype system at the PSC computer room, located in the Westinghouse Energy Centre in Pennsylvania.
