JAPANESE super computer 'K' on top


A Japanese supercomputer named ‘K' — capable of making 8.2 quadrillion calculations per second or equivalent to a million laptops working in tandem — has been named the most powerful system in the world.

The computer is three times faster than its Chinese rival that previously held the top position, a New York Times report said.

K, built by Fujitsu and located at the Riken Advanced Institute for Computational Science in Kobe, Japan, represents a giant leap forward in computing speed.

“It's a very impressive machine. It's a lot more powerful than the other computers,” the Times report quoted Jack Dongarra, a professor of electrical engineering and computer science at the University of Tennessee at Knoxville who keeps the official rankings of computer performance, as saying.

K pushed back the previous number one, Tianhe-1A supercomputer, at the National Supercomputing Centre in Tianjin, China, to second place.

Tianhe-1A was the first Chinese computer to be ranked on top.

The latest ranking of the top 500 computers released Monday, is determined by running a standard mathematical equation.

The winning computer was able to make 8.2 quadrillion calculations per second, or 8.2 petaflops per second, the report said. — IANS

The most authoritative ranking of supercomputers in the world Top-500 supercomputer headed Japanese "K", relegating to second Chinese "Tianhe-1A", said on Monday the site Top500.org.

According to the Top-500, Japanese supercomputer roughly three times more productive than the former leader of the ranking. Peak power of the "K" is 8.16 petaflops (petaflops – 1015 of floating-point operations per second), while the peak power of China's supercomputer is 2.56 petaflops (4.7 petaflops in the future). "This is a very impressive machine, it is more powerful than any computer that participates in the rating," - said Professor Jack Dongarra of the University of Tennessee The New York Times in response to a request to tell about the power of the Japanese supercomputer. He also said that the power of the "K" is approximately equal to the total productivity of a million modern desktop computers.

A computer built by Fujitsu and is located at the Institute of RIKEN in the Japanese city of Kobe. Now the "K" has 672 boxes (places, where chips are located in, board and computer cooling systems), and in the future, developers plan to increase the number of boxes to 800. One year of service of this supercomputer costs 10 million dollars.

 The third place in the Top-500 supercomputer took Jaguar (1,38 petaflops), located at the National Research Laboratory in Oak Ridge, USA (Oak Ridge National Laboratory). In fourth place - another Chinese supercomputer Nebulae (1,2 petaflops), in fifth place - the Japanese supercomputer Tsumabe 2.0 (1,19 petaflops).

The most powerful supercomputers in Russian, "Lomonosov", located at MSU, ranked the 13th place. His power is 420 teraflops (teraflops - a trillion operations with a floating point per second). Compared with the previous release of the rating of Top-500 (published twice a year - in November and June), "Lomonosov" climbed to four lines - in November, the computer was ranked 17th, while his power was 350 teraflops.

 Another Russian supercomputer, located at the Interdepartmental Supercomputer Center of the Russian Academy of Sciences, was at the 75th place with power in 140.16 teraflops. On the 84th place - the supercomputer of the Kurchatov Institute (101.21 teraflops). On the 86th place - the supercomputer of the South Ural State University, "SKIF-Aurora." The poert of this machine, according to the rating, is about 100 teraflops.

Supercomputers today are used in many ways: in calculating the formulas of new chemical substances (for ex., drugs), building structures, the aerodynamic features of planes and cars, designing new models of clothes etc.
