The Department of Energy's Oak Ridge National Laboratory has awarded a contract to Cray Inc. to increase the Jaguar supercomputer's science impact and energy efficiency. The upgrade, which will provide advanced capabilities in modeling and simulation, will transform the DOE Office of Science-supported Cray XT5 system, currently capable of 2.3 million billion calculations per second (petaflops), into a Cray XK6 system with a peak speed between 10 and 20 petaflops.
The new system will employ the latest AMD Opteron central processing units as well as NVIDIA Tesla graphics processing units — energy-efficient processors that accelerate specific types of calculations in scientific application codes. The last phase of the upgrade is expected to be completed in late 2012. The system, which will be known as Titan, will be ready for users in early 2013.
With 299,008 cores and 600 terabytes of memory for solving critical problems, Titan will continue the legacy of its predecessor as one of the nation's most powerful tools for science....The GPUs will allow users to begin modifying their scientific applications to work well with the new technology. In the second phase, to be performed in the second half of 2012, between 7,000 and 18,000 of NVIDIA's next-generation Tesla GPUs will be added to the system, increasing the peak performance to between 10 and 20 petaflops, depending on architectural options executed.
