Out to Crunch: U.S. Energy Department Unleashes Its Titan Supercomputer

In 2005 engineers at the U.S. Department of Energy's (DoE) Oak Ridge National Laboratory unveiled Jaguar, a system that would later be upgraded into a world-beating supercomputer. By 2011 it had grown to a room-size system that used seven megawatts of energy, ran nearly 225,000 processor cores and had a peak performance of 2.3 petaflops, or 2.3 quadrillion calculations per second. Topping Jaguar, albeit necessary to deliver ever more complex modeling of sophisticated energy challenges, would not be easy. [More]
