Fujitsu has presented its next generation supercomputer. Fujitsu K is the name of the system that is now being installed in Japan and the supercomputer will consist of no less than 800 server racks that will achieve a final performance over 10 petaflops, more than 6 times faster than the current king of Top 500, Jaguar.
Fujitsu K is the backbone of the the HPCI project (High-Performance Computing Infrastructure) and is expected to start operating in 2012. The construction has already started and when the system stands ready it will house over 80,000 Fujitsu SPARC 64 VIIIfx processors with 2.2 GHz clock frequency and eight cores for an until now unrecognied crunching power.
The Next-Generation Supercomputer nickname announced in July 2010. “K” here draws upon the Japanese word “Kei” for 1016, representing the system’s performance goal of 10 petaflops. In its original sense, “Kei” expresses a large gateway in Japanese, and it is hoped that the system will be a new gateway to computational science.
Each processor is capable of reaching up to 128 gigaflops and will also be energy efficient with 2.2 gigaflops per watt, which means that the processors will consume around 60 watt a piece. To keep temperatures at bay the systems are water-cooled, not just the processors but also other heat-emitting components.

The tens of thousands of processors and servers are connected in an internal network deviced and tailored by Fujitsu, which will distribute the loads to different parts of the system independently of each other, or simply make use of the full potential of the system.
