NEC SX-9 is fastest vector computer in the world
NEC Corporation is launching its SX series model SX-9, claiming it to be the world's fastest vector supercomputer with a peak processing performance of 839 TFLOPS (one trillion floating point operations per second).

The SX-9 features the first CPU capable of a peak vector performance of 102.4 GFLOPS (one billion floating point operations per second) per single core.

Vector supercomputers are built with high-speed processors called "vector processors" and are used for scientific/technical computation. Vector supercomputers deliver high performance in complex, large-scale computation, such as climates, aeronautics and space, environmental simulations, fluid dynamics, through the processing of array-handling with a single vector instruction.

In addition to the newly developed CPU, the SX-9 combines large-scale shared memory of up to 1TB (terabyte) and ultra high-speed interconnects achieving speeds up to 128GB/second.

Through these enhanced features, the SX-9 closes in on the PFLOPS (one quadrillion floating point operations per second) range by achieving 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 accomplished 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 company already sold more than 1,000 units of the SX series worldwide to organizations within these scientific fields.

This new computer features the addition of an arithmetic unit and an increased number of vector pipelines. This has resulted in the development of the fastest single-chip vector processor with a computing performance of 102.4 GFLOPS per single core, and a wide memory bandwidth of 256GB/s. With a single node incorporating up to 16 CPU, computing performance in excess of 1.6TFLOPS is achieved.

The SX-9 is loaded with SUPER-UX, compatible with the UNIX System V. SUPER-UX is equipped with flexible functions that can deliver more effective operational management compatible with large-scale multiple node systems.

“NEC’s vector supercomputers are being utilized in a wide array of fields, including advanced weather forecasting, aerospace, the environment and fluid dynamics, and have won praise from international and domestic universities and research organizations, as well as private corporations, for their high sustained performance and price competitiveness,” said Mr. Yoshikazu Maruyama, Senior Vice President and Member of the Board at NEC Corporation. “The SX-9 has been developed to meet the need for ultra-fast simulations of advanced and complex large-capacity scientific computing.”
