Unveiled at the 26th International Supercomputing Conference (ISC11) held in Hamburg, Kei Computer is now the world’s fastest supercomputer with a performance record of 8.162 petaflops, as measured by the LINPACK benchmark.
Kei ousted the previous record holder, Tianhe-1A, which was designed by the National University of Defense Technology (NUDT) in China and had a performance record of 2.507 petaflops.
Kei or simply K computer is designed by Fujitsu and Riken Advanced Institute for Computational Science in Japan, has a ability of performing 8.2 quadrillion calculations per second at the moment. The system has 672 cabinets house over 68,000 Fujitsu SPARC64 VIIIfx processors.
Running this system will cost 10$ million per year, which is comparatively less than the cost of previously built supercomputers. K is said to be the most energy efficient supercomputer ever built, after it achieved a computing efficiency ratio of 93.0%.
The system is still in its development phase and is expected to achieve LINPACK performance of 10 petaflops, when developed completely — expected to be in 2012. It will be used in fields like global climate research, meteorology, disaster prevention and medicine.
