By Betsy Mason | 由貝齊梅森| 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.一種新的作物的超級計算機是打破petaflop的速度障礙，推動高性能計算進入了一個新的境界，可以變化科學更深刻要比任何時候都要伽利略，導致研究人員說。 When the當 Top 500 list 500強名單 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.世界上最快的超級計算機宣布在國際超級計算機會議在得克薩斯州的奧斯汀，週一， IBM公司幾乎沒有設法固守榜首，抵擋的挑戰克雷。 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，這兩個競爭者打破petaflop的速度，執行1.105和1.059萬億次浮點運算每秒，第一兩台電腦這樣做。 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.這些電腦不僅是速度快於那些他們推進一步下降的名單，他們將啟用一種新型的科學，是無法做到的。 As recently described in Wired正如最近在有線描述 magazine, these massive number crunchers will push simulation to the forefront of science.雜誌，這些大量crunchers將推動模擬的前沿科學。 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.科學家們將能夠運行新的和更精確的巨大模型，複雜的現象：氣候模式將有顯著更高的分辨率和精度，新材料為高效率的能源傳輸將是發達國家和模擬沖壓發動機將達到一個新的複雜程度。 “The scientific method has changed for the first time since Galileo invented the telescope (in 1609),” said computer scientist Mark Seager of “科學的方法發生了變化以來的第一次伽利略發明了望遠鏡（於1609年） ， ”計算機科學家說，西格的馬克 Lawrence Livermore National Laboratory勞倫斯利弗莫爾國家實驗室 . 。 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.超級計算機已經取得了巨大的進步，過去十年左右的時間，逐步包裝的能力來處理越來越多的數據點，在日益複雜的方式。 It has enabled scientists to test theories, design experiments and predict outcomes as never before.它使科學家們進行測試的理論，設計實驗和預測的結果，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.但現在，新的一類petaflop的大規模機器準備帶來質的變化主要在科學的方式進行。 “The new capability allows you to do fundamentally new physics and tackle new problems,” said Thomas Zacharia, who heads up computer science at “新的能力允許你這樣做從根本上新的物理學和解決新問題， ”托馬斯說， Zacharia ，誰負責計算機科學 Oak Ridge National Laboratory in Tennessee橡樹嶺國家實驗室在田納西州 , home of the second place ，家庭的第二位 Cray XT5 Jaguar克雷XT5捷豹 supercomputer.超級計算機。 “And it will accelerate the transition from basic research to applied technology.” “這將加速轉型從基礎研究到應用技術。 ” 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，一個壯舉，似乎天文僅僅兩年前，不僅會允許更快的計算。 These computers will enable entirely new types of science that couldn’t have been done before.這些電腦將啟用全新類型的科學，不能一直在這樣做。 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.這新一代的petascale機器將科學模擬不僅僅是支持伊拉克的兩個主要分支科學，理論和實驗，並到前台。 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.而不只是假設進行測試與實驗和觀察，大規模的推斷和預測的事情，我們不能觀察或將不切實際的一項實驗，將成為中央到許多科學事業。 “It’s getting to the point where simulation is actually the third branch of science,” Seager said. “這是進入的地步模擬實際上是第三個分支科學” ，西格說。 “We say that nature is always the arbiter of truth, but it turns out our ability to observe nature is fundamentally limited.” “我們認為，性質永遠是真理的仲裁者，但事實證明我們的能力，觀察性質基本上是有限的。 ” Have Your Say: Supercomputers Break Petaflop Barrier, Transforming Science 你說：超級打破petaflop的障礙，轉化科學 Please read our請仔細閱讀我們的 posting guidelines before posting張貼在發布前的指導方針 . 。 Alternatively或者 you can discuss this report here你可以討論這份報告在這裡 . 。 Related News 相關新聞
