"This machine is very impressive," said Dongarra who is also Director of the Innovative Computing Laboratory. "It's much more powerful than other computers."
Super-computer named "K" it managed to shift the Tianhe-1A from the National Supercomputing Center in Tianjin, China, which now occupies the second position. The third ranking as the fastest computers reached the United States from Oak Ridge National Laboratory, Oak Ridge, Tennessee.
Super computer "K" was built at the Riken Fujitsu Advanced Institute for Computational Science in Kobe, Japan. This is where the "K" "blended" to become the fastest computers. Then, the computers are assembled in a factory Fujitsu, Hokuto City, Japan.
The race's fastest computer universe is followed by 500 participants. Each computer will be asked to perform standard mathematical equations. Computer "K" is able to perform up to 8.2 quadrillion calculations per second or 8.2 petaflops per second. "This is equivalent to connecting about one million desktop computers simultaneously," said Dongarra.
He said the supercomputer will be used for earthquake simulations, climate modeling, nuclear research and weapons development and testing. Computers can also be used to explore oil and a quick count of stock trading.
To build a superfast computer which of course will cost a lot and thousands of small computers that are connected in a data center. Computer "K" is built with 672 cabinets full of the system board.
Although the computer "K" is considered power-efficient, but the power needed this same machine with the power supply to 10 thousand homes and cost about U.S. $ 10 million per year.
Fujitsu plans to increase capacity to 800 super-computer that closet so he could work more quickly and capacity is also greater.
Behind the short name of the computer, "K" in Japanese is the abbreviation for the word "Kei" which means 10 quadrillion, the fastest unit in the computer calculations in one second.
Lately the countries in Asia began to show "fangs" in the technology world. China became a battering ram with the first super computer and is now followed by Japan. However, the United States still dominates the problem performance computer because it has five super-fast computers and into the top ten ranking.
Currently, said Dongarra, a computer system is being built even faster. Super computer called Blue Waters is now being developed at the University of Illinois, Urbana-Champaign.
