Abstract:   In 2011, Oak Ridge National Laboratory began an upgrade to Jaguar to convert it from a Cray XT5 into a Cray XK6 system named Titan. This is being accomplished in two phases. The first, which was completed in early 2012, was to replace all of the XT5 node boards with XK6 boards, including the AMD Opteron 6274 16-core processors, 600 terabytes of system memory, Cray’s new Gemini network, and 960 NVIDIA X2090 Tesla processors. In the second phase, ORNL will add 20 petaflops of NVIDIA’s next generation Kepler processor. This talk describes the Titan system, the challenges of developing a programming strategy and programming environment for the system, and present initial results comparing application performance on XT5 and XK6 nodes.
