OAK RIDGE, Tenn., Oct. 29 (UPI) -- Graphic processing units first created for computer gaming have been used to create one of the world's most powerful supercomputers, U.S. officials say.
The U.S. Department of Energy's Oak Ridge National Laboratory says its Titan supercomputer is capable of churning through more than 20,000 trillion calculations each second and will provide unprecedented computing power for research in energy, climate change, efficient engines, materials and other disciplines.
