专八阅读材料库之IBM夺回最快计算机桂冠

　　检测核武器库比模拟炸弹中的钚huang元素的反应要求要高得多。事实上，因为在核爆炸时，许多物质的反应难以预测，所以要检测核弹中的每一种物质。例如，计算机要能够检测出久置的核材料是否具有潜在的危险。

　　In the process， the computer will also help scientists unmask some of the 20th centurys great mysteries. Nuclear weapons， Schwoegler said， were built in the past pragmatically， not scientifically. In other words - the bombs worked， but the scientists building them were basing their construction on theories， instead of observation.

　　在这个过程，该计算机还将有助于科学家揭开上世纪一些重大的秘密。Schwoegler说，以前所造的核武器是实用性，而不是科学性的。换句话说，尽管核弹成功了，但是，建造核弹的科学家是根据理论而不是根据实际观察建造它们的。

　　ve seen scientists look at materials calculations on ASCI White and say， I knew that happened， but I couldnt prove it， Schwoegler said.

　　Schwoegler说：靠ASCI白计算机计算核弹物质的科学家们说，我知道发生了什么，但我不能证明它。

　　ASCI Purple is as fast as 50，000 top-of-the-line PCs performing calculations simultaneously. Its operating memory is 400，000 times greater than that of the average PC， and it can store data equivalent to the U.S. Library of Congress - 30 times over. At 100 teraflops - or 100 trillion calculations per second - it will be about eight times faster than its predecessor， ASCI White， and about three times faster than the worlds current No. 1 computer， The Earth Simulator in Yokohama， Japan. That NEC-built machine was installed earlier this year， knocking IBM out of the top spot.
