                    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 system, which will be known as Titan, will be ready for users in early 2013.
