Titan supercomputer unveiled at Oak Ridge National Laboratory
Capable of more than 20 petaflops of high-performance computing (HPC) power, the Cray XK7 supercomputer dubbed ‘Titan’ has been installed at the US Department of Energy’s Oak Ridge National Laboratory (ORNL). The world’s most powerful supercomputer for open science, Titan is a 200-cabinet Cray XK7 supercomputer with 18,688 compute nodes, each consisting of a 16-core AMD Opteron 6200 Series processor and a Nvidia Tesla K20 GPU accelerator. Titan was upgraded from the ‘Jaguar’ Cray XT5 supercomputer and its debut coincides with the launch of Cray’s XK7 system, which features the latest production hybrid supercomputing technologies.

By combining the features of the high-performance Gemini interconnect, the new Nvidia Tesla K20 GPUs and the 16-core AMD Opteron processors, Cray's XK7 systems are capable of scaling to more than 50 petaflops of performance. Additionally, they feature a unified CPU/GPU programming environment that provides users with validated tools, libraries, compilers and third-party software, fully integrated with each system's hardware. When combined with the Cray Linux Environment, the result is a hybrid supercomputer that blends scalable hardware, software and network.

Upgradeable from Cray XT4, Cray XT5, Cray XT6, Cray XE6 or Cray XK6 systems, the Cray XK7 supercomputer is available now. The system can be configured in a single cabinet with tens of compute nodes, to a multi-cabinet system with tens of thousands of compute nodes.
