NEC releases its latest commercial supercomputer model, boasting the “world’s best yet” when it comes to processing efficiency.


NEC’s new commercial supercomputer is called the SX-ACE, and it is part of NEC’s standard SX series of vector supercomputers.

This particular model however, is markedly different from other previous models, because it would be the first that would be installed with multi-core vector processors.

Each CPU core within a node of an SX-ACE unit is rated at 64 gigaFLOPS, and has a memory bandwidth of 64GB/s . The entire node has four cores total, giving it a total operation capacity of 256 gigaFLOPS and a memory bandwidth of 256GB/s. A single SX-ACE unit rack has about 64 of these nodes, with a maximum of 8 racks for a single lease order.

Vector processing-type supercomputers are mostly used in simulation and in various scientific research fields, most notably in meteorology and other fields of environmental science. Basically, processors of these supercomputers are best suited for any high level complex application where a significant number of data items or variables are needed to be processed in just one instruction line. This makes them different from computers that use (non-vector) multi-core processors, which mainly run different data lines on different sets of instructions.

Commercial availability (both in Japan and internationally) started last November 15, 2013. In Japan, they currently available for a monthly lease fee that is equivalent to about 45,000 USD.
