K – The Best Supercomputer In The World


A Japanese supercomputer, called “K”, currently occupies the first place on the list of the fastest of its kind in the world, announces the online publication Tgdaily.com.

The supercomputer, which is now only half built, has 672 racks equipped with a total of 68,544 processors. The computer has an incredibly high power, obtaining Linpack benchmark performance of 8.162 petaflop/s, and the calculation efficiency is 93%.

K surpassed the former leader of the fastest device, 500 such pc’s worldwide, Tianhe-1A, in China, which now ranks second with 2.6 petaflop/s. Last step of the podium is occupied by Jaguar, a Cray supercomputer to the U.S. Department of Energy at Oak Ridge National Laboratory, 1.75 petaflop/s.

The Japanese “K” will have over 800 shelves when it will be completed in 2012. When the system will be ready is estimated to have a petaflop computing power of 10/s. The device will be used by many research companies in many areas such as climate research, meteorological, disaster prevention and medicine.

On top of such systems in the world, Asians dominate the top 10. Thus, the 4th is Nebulae, the National Supercomputing Center of the Chinese city Shenzhen, with a capacity of 1.27 petaflop/s and on the fifth position is Tsubame 2.0, owned by Tokyo Institute of Technology, Japan, with a capacity of 1.19 petaflop/s.
