The whole system is an upgrade,” said Jack Wells in describing how Oak Ridge’s current Jaguar supercomputer is being transformed into Titan. ORNL is transitioning from Cray’s XT5 compute blades to their XK6 compute blades, which use hybrid chipsets comprised of AMD Opteron CPUs and NVIDIA Tesla GPUs. Application benchmarks conducted thus far have demonstrated that the XK6 is yielding performance improvements ranging from 50 percent to 230 percent compared with the XT5.
