Japanese K Computer Clocks 10.51 Petaflops

The K Computer installed at the Riken Advanced Institute for Computational Science in Japan has reached a milestone by clocking speeds of 10.51 petaflops.

According to c|net (opens in new tab), the Top500 list of the world's fastest supercomputers remains unchanged this time but the fastest supercomputer in the world managed to break its own record to clock higher speeds.

The K Computer had entered the list as the world's fastest super computer with speeds of 8.16 petaflops, which was significantly more than 2.57 petaflops clocked by the Chinese Tianhe-1A that was pushed to the second spot by K.

Using all of its 705,024 Fujitsu Sparc64 processor cores, The K computer managed to reach record breaking speeds of 10.51 petaflops.

"The K Computer is the first supercomputer to achieve a performance level of 10 Petaflop/s, or 10 quadrillion calculations per second. In June 2011, the partially built K computer had taken the No. 1 position with a performance of 8.16 Petaflop/s," Top500 (opens in new tab) noted.

"Contrary to many other recent very large systems, it does not utilize graphics processors or other accelerators. The K Computer is also one of the most energy efficient systems on the list," the organisation added.
