K computer
From Wikipedia, the free encyclopedia
K computer|

A cabinet of RIKEN's K computer prototype manufactured by Fujitsu| Active| Operational 2011|
Sponsors| MEXT,  Japan|
Operators| Fujitsu|
Location| RIKEN Advanced Institute for Computational Science| Architecture| 68,544 SPARC64 VIIIfx processors, Tofu interconnect, Linux-based enhanced operating system| Speed| 8.162 petaflops (Rmax)|

Ranking| TOP500: 1, June 2011|
The K computer, named after the Japanese word "kei" (京?), which stands for 10 quadrillion,[1]is a supercomputer being produced by Fujitsu at the RIKEN Advanced Institute for Computational Science campus in Kobe, Japan.[2][3][4] -------------------------------------------------

]Specifications
On 20 June 2011, the TOP500 Project Committee announced that K topped the LINPACKbenchmark with the performance of 8.162 petaflops, or 8.162 quadrillion calculations per second, with a computing efficiency ratio of 93.0%, making it the fastest supercomputer in the world.[3][5][6][4] The previous record holder was the Chinese National University of Defense Technology's Tianhe-1A, which performed at 2.507 petaflops.[2] The list is revised semiannually, and the rankings change frequently, indicating the speed at which computing power is increasing.[3] The system is still under construction and will enter service in November 2012 with 864 cabinets. It currently uses 68,544 2.0GHz 8-core SPARC64 VIIIfx processors packed in 672 cabinets, for a total of 548,352 cores, manufactured by Fujitsu with 45 nm CMOS process technology.[7]Each cabinet contains 96 compute nodes in addition to 6 IO nodes. Each compute node contains a single processor and 16 GB of memory. Its water cooling system minimizes failure rate and power consumption. The K uses a special six-dimensional torus network interconnect...
