No. 1 K Computer: Japan

The K Computer leading the race of Super Computing with the best performance of gigantic 8.162 petaflops. The K Computer is a joint development of RIKEN and Fujitsu Company both of which are 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 TOP500-ranked K computer system, currently in the configuration stage, has 672 computer racks equipped with a current total of 68,544 CPUs. This half-built system achieved the world’s best LINPACK benchmark performance of 8.162 petaflops, to place it at the head of the TOP500 list.
