Titan: World's Fastest Supercomputer Unleashed
2012-10-29 10:21:25

Michael Harper for redOrbit.com — Your Universe Online The Oak Ridge National Laboratory (ORNL) has created a machine capable of doing the unthinkable. In fact, it´s capabilities not only sound impossible, they sound fictional. By combining traditional CPUs with graphical processing units (GPUs), the Titan Supercomputer capable of spitting out 20 petaflops, making it 10 times more powerful than ORNL´s previous Jaguar supercomputer. For the uninitiated, a petaflop, says...

For the first time, climate scientists from across the country have successfully incorporated the nitrogen cycle into global simulations for climate change, questioning previous assumptions regarding carbon feedback and potentially helping to refine model forecasts about global warming. The results of the experiment at the Department of Energy's Oak Ridge National Laboratory and at the National Center for Atmospheric Research are published in the current issue of Biogeosciences. They...

If everyone in the world performed one mathematical calculation per second, it would take 650 years to do what the new supercomputer at Oak Ridge National Laboratory could do in one day. Nicknamed "Jaguar" by scientist, this $100 million computer is the world's fastest computer for unclassified scientific research.  This computer performs 1 quadrillion mathematical calculations per second, making it 55,000 times faster than your typical PC. The only supercomputer faster is devoted to...
