Washington: New supercomputer Titan can process
more than 20,000 trillion calculations, or 20 petaflops, in a mere blink
by employing a series of graphic processing units first created for
computer gaming.
Launched by the Oak Ridge National Lab (ORNL), Titan will be 10 times as powerful as ORNL's last world-leading system, Jaguar, overcoming power and space limitations inherent in the previous generation of high-performance computers.
Using a grid of 14-km cells, the new system will be able to simulate from one to five years per day of computing time, up from the three months or so that Jaguar was able to churn through in a day, according to an ORNL statement.
Titan, which is supported by the US Department of Energy, will provide unprecedented computing power for research in energy, climate change, efficient engines, materials and other disciplines and pave the way for a wide range of achievements in science and technology.
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 graphics processing unit (GPUs) will allow Titan to occupy the same space as its Jaguar predecessor while using only marginally more electricity.
"One challenge in supercomputers today is power consumption," said Jeff Nichols, associate lab director for computing and computational sciences.
