Red Storm (computing)

Red Storm is a from 2004 by Cray Inc. as successor of ASCI Red for Sandia National Laboratories in Albuquerque (New Mexico) built supercomputer. He is the first model with the Cray XT3 architecture for high-performance computers and is used for simulation tasks, including under the U.S. Advanced Simulation and Computing Program.


The system consists of 14,348 compute nodes, each consisting of a dual-core AMD Opteron processor for computation tasks and a PowerPC 440- based processor ( SeaStar ) exist for communication tasks. Is a MPP system with distributed memory and MIMD architecture.

The operating system is on the computational processors Catamount (based on that used in ASCI Red Cougar ) and to the communications processors, a variant of Linux.

The system occupies an area of ​​about 300 square meters and has a power consumption of approximately 2.2 MW.


In the first phase, from 2004 onwards, the system reached 10,386 at 2.0 GHz clocked single-core Opterons a Linpack performance of approximately 42 teraflops. Following the increase in the number of nodes to 14,348 and the conversion to 2.4 GHz dual-core Opterons (2006 ) the total output rose to 101.4 teraflops ( 124.4 TFLOPS peak power ), which Red Storm Rank 3 (June 2007) the TOP500 list of supercomputers behind the Blue Gene / L at Lawrence Livermore National Laboratory ( 280.6 TFLOPS ) and the "Jaguar" at Oak Ridge National Laboratory occupied ( 101.7 TFLOPS ).
