中国天河2号将成全球最快超级计算机

唐加拉是田纳西大学(University of Tennessee)的教授，也是橡树岭国家实验室的工作成员。他说，中国官员称，该系统理论上的性能峰值是每秒运算54.9千万亿次。他说，在Linpack标准测试中可达到30.65千万亿次，相比之下，橡树岭实验室的系统可达到17.59千万亿次。

The U.S. has previously responded to such challenges, including a system from Japan that temporarily held the top speed ranking. But the next U.S. supercomputer that could challenge the Tianhe-2 isn't expected until 2017, said Horst Simon, another supercomputer expert who is deputy director at Lawrence Berkeley National Laboratory.

美国之前曾经回应过此类挑战，包括运算速度曾经排名第一的来自日本的系统。但是另一名超级计算机专家西蒙(Horst Simon)说，美国能够挑战天河2号的下一台超级计算机预计到2017年才会出现。西蒙是劳伦斯伯克利国家实验室(Lawrence Berkeley National Laboratory)的副主任。

'If anybody believes that the Chinese are just in there for a stunt, this machine has proven them wrong,' Mr. Simon said.

西蒙说，如果有人觉得中国人研究超级计算机只是噱头，这台计算机可以证明他们错了。

He argued that the U.S. government has invested sporadically in supercomputers lately, while Chinese agencies have spent steadily. 'In some areas where there has been a tradition of U.S. leadership, the Chinese are out there to really be in the race and win,' Mr. Simon said.
