RIKEN and Fujitsu have taken the No. 1 position for the "K computer"(1) on the 38th TOP500(2) list announced today in the US (November 14, PST), for a consecutive two terms in a row. The K computer, currently under joint development, was designated as being the world's fastest supercomputer. The TOP500 was previously announced in June 2011.
The TOP500-ranked K computer system has 864 computer racks equipped with a total of 88,128 CPUs. The system achieved the world's best LINPACK(3) benchmark performance of 10.51 petaflops (quadrillion floating-point operations per second) with a computer efficiency ratio of 93.2%.

The certification ceremony will be held at SC11, the International Conference for High Performance Computing, Networking, Storage and Analysis, being held in Seattle, Washington in the United States. The ceremony is scheduled to take place on November 15, 2011 PST (November 16, 2011 in Japan).
 K computer:
The K computer, which is being jointly developed by RIKEN and Fujitsu, is part of the High-Performance Computing Infrastructure (HPCI) initiative led by Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT). Configuration of the K computer began in the end of September 2010, with availability for shared use scheduled for 2012. The "K computer" is the nickname RIKEN has been using for the supercomputer of this project since July 2010. "K" comes from the Japanese Kanji letter "Kei" which means ten peta or 10 to the 16th power. The logo for the K computer based on the Japanese letter for Kei, was selected in October 2010. In its original sense, "Kei" expresses a large gateway, and it is hoped that the system will be a new gateway to computational science.
The TOP500 list is a project that periodically ranks the 500 fastest supercomputers in the world, using LINPACK as a benchmark. The project, begun in 1993, publishes current rankings twice a year (in June and November). http://www.top500.org/
A program developed by J. Dongarra, Ph.D., of the University of Tennessee, for solving a system of linear equations using matrix computation. It is the benchmark program used to create the TOP500 list, which ranks the performance of the world's supercomputers (announced in June and November of every year).
RIKEN is Japan's flagship research institute devoted to basic and applied research. Over 2500 papers by RIKEN researchers are published every year in reputable scientific and technical journals, covering topics ranging across a broad spectrum of disciplines including physics, chemistry, biology, medical science and engineering. RIKEN's advanced research environment and strong emphasis on interdisciplinary collaboration has earned itself an unparalleled reputation for scientific excellence in Japan and around the world.
