Oak Ridge National Laboratory Debuts Titan Supercomputer
November 7, 2012
The Energy Department's Oak Ridge National Laboratory Titan supercomputer will be 10 times faster than the previous fastest Energy Department computer.
The Energy Department's Oak Ridge National Laboratory (ORNL) on October 29 debuted the Titan supercomputer, a system capable of a theoretical peak performance exceeding 20 trillion calculations per second (or 20 petaflops). Titan employs a family of processors called graphic processing units (GPU), first created for computer gaming, and will be 10 times more powerful than ORNL's last world-leading system, Jaguar.
Titan will provide unprecedented computing power for research in energy, climate change, efficient engines, materials, and other disciplines and will pave the way for a wide range of achievements in science and technology. Titan utilizes a Cray XK7 system contains 18,688 nodes, each holding a 16-core AMD Opteron 6274 processor and an NVIDIA Tesla K20 GPU accelerator. Titan also has more than 700 terabytes of memory. The combination of central processing units, the traditional foundation of high-performance computers, and more recent GPUs will allow Titan to occupy the same space as its Jaguar predecessor while using only marginally more electricity.
