ORNL sets its new Titan Supercomputer to work
29 October 2012
The US Department of Energy's Oak Ridge National Laboratory has launched Titan, a supercomputer capable of more than 20,000 trillion calculations per second.
Titan will be ten times more powerful than ORNL's last world-leading system, Jaguar, while overcoming power and space limitations inherent in the previous generation of high-performance computers. The system is expected to provide unprecedented computing power for research in energy, climate change, efficient engines, materials and other disciplines.
The Cray XK7 system contains 18,688 nodes, with each holding a 16-core AMD Opteron 6274 processor and a NVIDIA Tesla K20 graphics processing unit (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 at a marginally higher power consumption.
