By Betsy Mason | 由贝齐梅森| 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.一种新的作物的超级计算机是打破petaflop的速度障碍，推动高性能计算进入了一个新的境界，可以变化科学更深刻要比任何时候都要伽利略，导致研究人员说。 When the当 Top 500 list 500强名单 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.世界上最快的超级计算机宣布在国际超级计算机会议在得克萨斯州的奥斯汀，周一， IBM公司几乎没有设法固守榜首，抵挡的挑战克雷。 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.但是，这两个竞争者打破petaflop的速度，执行1.105和1.059万亿次浮点运算每秒，第一两台电脑这样做。 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.这些电脑不仅是速度快于那些他们推进一步下降的名单，他们将启用一种新型的科学，是无法做到的。 As recently described in Wired正如最近在有线描述 magazine, these massive number crunchers will push simulation to the forefront of science.杂志，这些大量crunchers将推动模拟的前沿科学。 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.科学家们将能够运行新的和更精确的巨大模型，复杂的现象：气候模式将有显着更高的分辨率和精度，新材料为高效率的能源传输将是发达国家和模拟冲压发动机将达到一个新的复杂程度。 “The scientific method has changed for the first time since Galileo invented the telescope (in 1609),” said computer scientist Mark Seager of “科学的方法发生了变化以来的第一次伽利略发明了望远镜（于1609年） ， ”计算机科学家说，西格的马克 Lawrence Livermore National Laboratory劳伦斯利弗莫尔国家实验室 . 。 Supercomputing has made huge advances over the last decade or so, gradually packing on the ability to handle more and more data points in increasingly complex ways.超级计算机已经取得了巨大的进步，过去十年左右的时间，逐步包装的能力来处理越来越多的数据点，在日益复杂的方式。 It has enabled scientists to test theories, design experiments and predict outcomes as never before.它使科学家们进行测试的理论，设计实验和预测的结果，是前所未有的。 But now, the new class of petaflop-scale machines is poised to bring about major qualitative changes in the way science is done.但现在，新的一类petaflop的大规模机器准备带来质的变化主要在科学的方式进行。 “The new capability allows you to do fundamentally new physics and tackle new problems,” said Thomas Zacharia, who heads up computer science at “新的能力允许你这样做从根本上新的物理学和解决新问题， ”托马斯说， Zacharia ，谁负责计算机科学 Oak Ridge National Laboratory in Tennessee橡树岭国家实验室在田纳西州 , home of the second place ，家庭的第二位 Cray XT5 Jaguar克雷XT5捷豹 supercomputer.超级计算机。 “And it will accelerate the transition from basic research to applied technology.” “这将加速转型从基础研究到应用技术。 ” Breaking the petaflop barrier, a feat that seemed astronomical just two years ago, won’t just allow faster computations.打破petaflop的屏障，一个壮举，似乎天文仅仅两年前，不仅会允许更快的计算。 These computers will enable entirely new types of science that couldn’t have been done before.这些电脑将启用全新类型的科学，不能一直在这样做。 This new generation of petascale machines will move scientific simulation beyond just supporting the two main branches of science, theory and experimentation, and into the foreground.这新一代的petascale机器将科学模拟不仅仅是支持伊拉克的两个主要分支科学，理论和实验，并到前台。 Instead of just hypotheses being tested with experiments and observations, large-scale extrapolation and prediction of things we can’t observe or that would be impractical for an experiment, will become central to many scientific endeavors.而不只是假设进行测试与实验和观察，大规模的推断和预测的事情，我们不能观察或将不切实际的一项实验，将成为中央到许多科学事业。 “It’s getting to the point where simulation is actually the third branch of science,” Seager said. “这是进入的地步模拟实际上是第三个分支科学” ，西格说。 “We say that nature is always the arbiter of truth, but it turns out our ability to observe nature is fundamentally limited.” “我们认为，性质永远是真理的仲裁者，但事实证明我们的能力，观察性质基本上是有限的。 ” Have Your Say: Supercomputers Break Petaflop Barrier, Transforming Science 你说：超级打破petaflop的障碍，转化科学 Please read our请仔细阅读我们的 posting guidelines before posting张贴在发布前的指导方针 . 。 Alternatively或者 you can discuss this report here你可以讨论这份报告在这里 . 。 Related News 相关新闻
