Worlds Fastest Computer

The fastest computer in the world belongs to the Chinese. The Tianjin National Supercomputer Center's Tianhe-1A system benchmarked a performance of 2.67 petaflops (A petaflop is 1,125,899,906,842,624 calculations per second - a thousand trillion or quadrillion), surpassing the U.S. Department of Energy's Cray XT5 Jaguar system at a slow 1.75 petaflops. IBM is building two mega machines, a 10 petaflops and a 20 petaflops system, both to be running in 2012. We are approaching the Singularity faster than predicted.

A human brain's probable processing power is around 100 teraflops (100 trillion calculations per second), according to Hans Morvec, principal research scientist at the Robotics Institute of Carnegie Mellon University. We do have one edge over computers, they have not been able to build a computer that fast as small as our brain. . .  yet.

Less than forty years ago, we were wondering when the computer would be able to do a million operations a second. Less than three years ago we hailed the fastest computer for running teraflops (trillion floating point operations per second).

BTW, IBM's Watson, of Jeopardy fame, runs at a miserably slow speed of 80 teraflops.
