The said K Computer system has 672 computer racks, 68,544 CPUs and 8.162 petaflops calculation speed. It won the fastest supercomputer in the Top500 ranking of the world’s supercomputers considering that is only half completed, surpassing the 2.507 petaflops of China’s Tianhe-1A that won the 2010 fastest supercomputer in world. K Computer system is expected to be completed by the year 2012 with a performance to reach 10 petaflops. But with the U.S. aiming to home the fastest computer title once again with their “Titan” computer, to be built by Cray Computer with a predicted speed of 20 petaflops, let’s see if K Computer can maintain its title by the year 2012. The Titan computer first stage of computing array is expected by the end of 2011.
* petaflop = quadrillion floating-point operations per second.
