（press release ）

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 (quadrillion floating-point operations per second), to place it at the head of the TOP500 list. In addition, the system has recorded high standards with a computing efficiency ratio of 93.0%. This is the first time since June 2004, when the 'Earth Simulator' took first place, that a Japanese supercomputer has been ranked first on the TOP500 list.
