World's Fastest

Us computer named World's fasted. A Cray super computer at the US Government's Oak Ridge National Laboratory has been named the world's fastest. It overtook an IBM supercomputer at another American research center. Titan, a Cray XK7 system installed at Oak Ridge achieved 17.59 petaflops(quadrillions of calculations per second). The system is funded by the United States Department of Energy, and is used for research in energy, climate change, efficient engines, materials and other advanced scientific research.

Titan knocked the IBM Sequoia at the Lawrence Livermore National Laboratory, California, to second place. Sequoia, which was declared the world's fastest system in June 2012, could manage only 16.32 petaflops in the contest. In the top five, the others were Fujitsu's K computer in Kobe, Japan; an IBM  BlueGene/q system named Mira in Chicago  USA; and another IBM BlueGene/Q system named Juqueen in Germany. The survey found that 251 of the fastest 500 systems in the world were in USA, 105 in Europe and 123 in Asia, including 72 in China.
