[Shacs] And now... the PetaFlop Computer

[McGuire, Timothy]

More than one quadrillion floating-point calculations per second:

    A new crop of supercomputers is breaking down the petaflop speed barrier, pushing high-performance computing into a new realm that could change science more profoundly than at any time since Galileo, leading researchers say.

    When the Top 500 list of the world’s fastest supercomputers was announced at the international supercomputing conference in Austin, Texas, on Monday, IBM had barely managed to cling to the top spot, fending off a challenge from Cray. But both competitors broke petaflop speeds, performing 1.105 and 1.059 quadrillion floating-point calculations per second, the first two computers to do so.

    These computers aren’t just faster than those they pushed further down the list, they will enable a new class of science that wasn’t possible before. As recently described in Wired magazine, these massive number crunchers will push simulation to the forefront of science.

    Scientists will be able to run new and vastly more accurate models of complex phenomena: Climate models will have dramatically higher resolution and accuracy, new materials for efficient energy transmission will be developed and simulations of scramjet engines will reach a new level of complexity.

    “The scientific method has changed for the first time since Galileo invented the telescope (in 1609),” said computer scientist Mark Seager of Lawrence Livermore National Laboratory.
