[attach]14875[/attach]

近日，美国能源部的 Oak Ridge National Laboratory （橡树岭国家实验室）发布了他们最新最好的超级电脑 Titan.（巨人）这个电脑必它上一任快十倍。这个电脑是为大量计算需要提供解决之道而生的，比如，运算气候变化的模型。呵呵，当然了，如果你想和它过过招下一盘跳棋也随你。

Ars Technica 给我们讲述了这台神器的组成：

操作系统是 Cray XK7 , Titan 有 18,688 个计算单元, 每个单元有一个 AMD Opteron 6274 处理器 NVIDA Tesla K20 GPU 加速器。 The NVIDA GPUs 主要承担计算模型所需的工作，而AMD处理器是用来管理他们的。名副其实，Titan 很大，占地4,352 平房英尺。

它也许还不能成为《终结者I,II,III》里对人类宣战的天网系统，也和《黑客帝国I,II,III》里主宰人类的电脑差距很远，甚至连《严厉的月亮》里的迈克洛夫特都比不上。但确实是我们人类做出的最接近这些毁灭人类、或者和人类开玩笑的电脑的东西了。

Though it only usurped the title of world’s fastest supercomputer this summer, IBM’s Sequoiamight have already met its match. The Department of Energy’s Oak Ridge National Laboratory today powered up their latest and greatest supercomputer: Titan. If the name alone doesn’t do it for you, perhaps the fact that Titan is ten times more powerful than its immediate predecessor will. The supercomputer’s set to provide its massive computing ability to issues like climate change, but it can probably also play a mean game of Solitaire.

Ars Technica breaks it down:

Based on the Cray XK7 system, Titan consists of 18,688 computing nodes, each with an AMD Opteron 6274 processor and an NVIDA Tesla K20 GPU accelerator. The NVIDA GPUs provide most of the computing horsepower for simulations, with the Opteron cores managing them. True to its name, Titan is big—it takes up 4,352 square feet of floorspace in ORNL’s National Center for Computational Sciences.

It might not be Skynet, but it’s about as close as we’ve come yet. We hope to use its power for good, though, like Boromir. If that’s not enough references for you, this video includes all the sounds from the Titan unit found in Command & Conquer 3: Kane’s Wrath. You’re welcome.
