NEC SX-9



NEC SX-9 Press Release

NEC SX-9 is to be the world's fastest vector supercomputer with a peak processing performance of 839 TFLOPS. The SX-9 features the world's first CPU capable of a peak vector performance of 102.4 GFLOPS per single core.

In addition to the newly developed CPU, the SX-9 combines large-scale shared memory of up to 1TB and ultra high-speed interconnects achieving speeds up to 128GB/second. Through these enhanced features, the SX-9 closes in on the PFLOPS range by realizing a processing performance of 839 TFLOPS. The SX-9 also achieves an approximate three-quarter reduction in space and power consumption over conventional models. This was achieved by applying advanced LSI design and high-density packaging technology.

In comparison to scalar servers incorporating multiple general-purpose CPUs, the vector supercomputer offers superior operating performance for high-speed scientific computation and ultra high-speed processing of large-volume data. The enhanced effectiveness of the new product will be clearly demonstrated in fields such as weather forecasting, fluid dynamics and environmental simulation, as well as simulations for as-yet-unknown materials in nanotechnology and polymeric design.

The SX-9 will be showcased at SC07 (Supercomputing 2007), the world's largest supercomputing exposition, in Reno, Nevada from November 10 - 16. It will also be on display at iExpo2007 (NEC's own personal exhibition), at Tokyo's Big Site from December 5 - 7.

The machine will be built in Kobe in western Japan and operated by public research institute Riken.

A computer cluster is a group of loosely coupled computers that work together closely so that in many respects they can be viewed as though they are a single computer. The components of a cluster are commonly, but not always, connected to each other through fast local area networks. Clusters are usually deployed to improve performance and/or availability over that provided by a single computer, while typically being much more cost-effective than single computers of comparable speed or availability.



The TOP500 organization's semiannual list of the 500 fastest computers usually includes many clusters. TOP500 is a collaboration between the University of Mannheim, the University of Tennessee, and the National Energy Research Scientific Computing Center at Lawrence Berkeley National Laboratory. As of June 2007, the top supercomputer is the Department of Energy's IBM BlueGene/L system with performance of 280.6 TFlops.

Top500:

373 Clusters (74,60 %)

107 MPPs (21,40%)

20 Constellations (4,00%)

The TOP500 project ranks and details the 500 most powerful publicly-known computer systems in the world. The project was started in 1993 and publishes an updated list of the supercomputers twice a year. The project aims to provide a reliable basis for tracking and detecting trends in high-performance computing and bases rankings on HPL, a portable implementation of the High-Performance LINPACK benchmark for distributed-memory computers.

The TOP500 list is compiled by Hans Meuer of the University of Mannheim, Germany, Jack Dongarra of the University of Tennessee, Knoxville, Erich Strohmaier and Horst Simon of NERSC/Lawrence Berkeley National Laboratory.

The list is updated twice a year. The first of these updates always coincides with the International Supercomputer Conference in June, the second one is presented in November at the IEEE Super Computer Conference in the USA.

The Systems Ranked #1 Since 1993

* IBM Blue Gene/L (since 2004.11)
* NEC Earth Simulator (2002.06 - 2004.11)
