The U.S. Department of Energy's Oak Ridge National Laboratory launched a new era of scientific supercomputing Monday with Titan, a system capable of churning through more than 20,000 trillion calculations each second — or 20 petaflops — by employing a family of processors called graphic processing units first created for computer gaming.
Titan will be 10 times more powerful than ORNL's last world-leading system, Jaguar, while overcoming power and space limitations inherent in the previous generation of high-performance computers
