Most powerful supercomupter

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
