XT3 Supercomputer

The XT3 supercomputer is a massively parallel processing (MPP) system that advances the scalability and sustained application performance of the T3D and T3E systems. The supercomputer’s architecture, co-designed with Sandia National Laboratories as part of the $90 million “Red Storm” system contract, delivers scalable application performance across a range of configurations from 200 to 30,000 processors, with peak performance of up to 144 teraflops (trillions of calculations per second). When fully installed, “Red Storm” will have over 40 peak teraflops of performance, more than 11,000 AMD Opteron processors, and 240 terabytes of disk storage. Features include a 3-D torus direct connected processor (DCP) architecture that tightly links processors to nearest neighbors, a high-bandwidth, low-latency interconnect with embedded communications processing and routing, offering total interconnect bandwidth of more than 100 terabytes/second, and high-speed global I/O that is scalable to over 100 gigabytes/second of I/O (input/output) bandwidth.
