What is the world's most powerful computer?

The IBM 'Roadrunner', which has the ability to process one million billion calculations per second. There is only one 'Roadrunner', which is owned by the U.S. Department of Energy's National Nuclear Security Administration. http://www.forbes.com/2009/01/28/most-powerful-things-business-power08_0128_powerful.html May 08 09, 8:29 PM

The chicken has it right. http://www.top500.org/system/details/9707 It's installed at Los Alamos National Laboratory. http://www.lanl.gov/news/index.php/fuseaction/home.story/story_id/13602 Interestingly, it uses Linux as its operating system. May 08 09, 9:10 PM

The Roadrunner computer is a U.S. Military supercomputer that processes over 1.026 quadrillion calculations per second. http://www.mahalo.com/Roadrunner_Computer Reached 1.6 petaflops in June of 2008 making it the world's fastest computer. Built by IBM for the U.S. Department of Energy. Twice as fast as the IBM Blue Gene/L. Cost: $133 million. Build at Los Alamos National Laboratory in Los Alamos, New Mexico. May 08 09, 9:56 PM

A super computer called blue gene does a trillion calculations per second http://inhome.rediff.com/money/2005/jun/23super.htm May 09 09, 7:33 AM

Roadrunner can do one quadrillion (US style) floating point operations ("flops") per second. "For the Roadrunner supercomputer, operating at petaflop/s performance means the machine can process a million billion calculations each second." http://www.lanl.gov/news/index.php/fuseaction/home.story/story_id/13602 Blue Gene, on the other hand, does not reach that level of performance: "... reached a peak processing speed of 136.8 teraflops (trillion calculations per second), in testing." That makes Roadrunner at least 7 times faster. The reference quoted for Blue Gene is dated 2005, therefore very outdated. May 09 09, 10:08 AM
