What: Tianhe-1A, supposedly the world's fastest computer, was unveiled by China Oct. 28. It weighs about 155 tons, comprises of 103 computer racks that cover more than 17,000 square feet and consumes about 4.04 megawatts of electricity. Instead of using central processing units, developers integrated graphic processing units into the computer, cutting power consumption and increasing efficiency three-fold. The computer can do 2.5 thousand trillion calculations per second, surpassing the XT5 Jaguar at the Oak Ridge National Laboratory in Tennessee by about 47 percent.
Who: It was designed by the National University of Defense Technology in China and cost about $88 million.
The Future: This super computer will allow scientific research to be performed not only faster but also more accurately - affecting fields such as biomedicine, energy and weather forecasting. The Top 500 list, which is scheduled to be released at the International Supercomputing Conference in Germany, will make the title of this megacomputer official.
