Titan - Early Experience with the Titan System at Oak Ridge National Laboratory

SESSION: Fielding Large Scale Systems

EVENT TYPE: Keynote and Invited Talks

TIME: 11:15AM - 12:00PM

SESSION CHAIR: Bronis R. de Supinski

Presenter(s):Arthur S. Bland


In 2011, Oak Ridge National Laboratory began a two phase upgrade to convert the Cray XT5 Jaguar system into a Cray XK6 system named Titan. The first phase, completed in early 2012, replaced all XT5 node boards with XK6 boards, including the AMD Opteron 6274 16-core processors, 600 terabytes of system memory, Crays new Gemini network, and 960 NVIDIA X2090 Fermi processors. The second phase will add 20 petaflops of NVIDIAs next generation K20 Kepler processor. The most important aspect of the Titan project has been developing a programming strategy to allow the applications to run efficiently and effectively on the accelerators, while maintaining compatibility with other architectures. ORNLs Center for Accelerated Applications Readiness has worked for over two years to implement this strategy on several key Department of Energy applications. This talk describes Titan, the upgrade process, and the challenges of developing its programming strategy and programming environment.
