The "K Supercomputer," being jointly developed by RIKEN and Fujitsu, has achieved a world's best performance on the LINPACK benchmark program, logging 8.162 petaflops (quadrillion floating-point operations per second), and a computing efficiency rating of 93.0% to place it at the head of the TOP500 list. The K computer system, currently in the configuration stage, has 672 computer racks equipped with a current total of 68,544 CPUs. When it goes into full shared-use service in November 2012, as a part of the High-Performance Computing Infrastructure (HPCI) initiative led by Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT) the K computer will comprise over 800 computer racks—each equipped with ultrafast and energy-efficient CPUs—that access into a network capable of an immense amount of interconnectivity. The supercomputer system brings together leading-edge technologies for high performance and high reliability.
