AT OAK RIDGE.........ORNL MAKING PROGRESS TOWARD TITAN SUPERCOMPUTER

摘要

Oak Ridge National Laboratory, home of the Department of Energy's Leadership Computing Facility and a stable of top supercomputers, has taken the next step toward a 20-petaflops (or greater) machine that will be called Titan and possibly become the world's fastest computer in coming months. The new Cray machine, which has a hybrid architecture that is being rebuilt in the existing cabinets of its predecessor, Jaguar, will be boosted by the addition of Nvidia's next generation Kepler graphical processing units (GPUs) that will complement the AMD CPUs already installed in the 200-cabinet supercomputer. Jeff Nichols, ORNL's associate lab director for scientific computing, confirmed that the lab had received its initial delivery of Kepler GPUs and has installed them in a "development platform" that was made up of some of the Jaguar units and separated in order to test the new architecture. "We have received 32 Keplers and put them in our development platform," Nichols said. "Everything is going as [or better than] expected."
