中国天河2号将成全球最快超级计算机

中国2010年对外公布的一台超级计算机曾短暂成为世界运算速度最快的计算机。但是美国的研究机构又推出了更快的硬件，即田纳西州橡树岭国家实验室(Oak Ridge National Laboratory)的一台叫做“泰坦”(Titan)的计算机。

The new Chinese system─called the Tianhe-2, or Milkyway-2─uses two different kinds of computer chips from Intel Corp. INTC -2.60% as well as some homegrown circuitry, according to Jack Dongarra, a U.S. supercomputer expert who saw the system last week. He published details about the machine that were reported earlier by the publication HPCwire.

根据上周亲眼看到这一系统的美国超级电脑专家唐加拉(Jack Dongarra)说，中国开发的新系统叫做“天河2号”，使用了来自英特尔的两种不同电脑芯片以及一些国产的电路系统。他发表了这台计算机的具体信息，这些信息早些时候已经被HPCwire网站报道。

'It's a real system,' said Mr. Dongarra in an interview Wednesday. 'It seems to be ready for production.'

唐加拉周三接受采访时说，这是一个真正的系统。它似乎已经可以投入生产。

Mr. Dongarra, a professor at the University of Tennessee who is also on the Oak Ridge research staff, said Chinese officials put the system's theoretical peak performance at 54.9 quadrillion operations per second─or petaflops, in industry parlance. It reached 30.65 petaflops in a standard test known as Linpack, he said, compared with 17.59 petaflops for the Oak Ridge system.
