外文标题：China’s Tianhe-2 named world’s fastest supercomputer

NEW DELHI: China’s Tianhe-2 supercomputer, aka Milkyway-2, recently measured at speeds of nearly 31 petaflops surpassing the current record holder by 74 per cent, Ars Technica, the technology magazine reported. And it was not even running at its full capacity!
The numbers were revealed by University of Tennessee professor Jack Dongarra, who introduced the computer speed measuring Linpack benchmarks, and who helps compile the biannual Top500 list of the world’s most powerful supercomputers.
One petaflop is a thousand trillion or one followed by 15 zeroes number of operations per second.
新德里：据科技杂志《Ars Technica》称，中国天河2号超级计算机最近测得速度接近每秒31千万亿次，超过当前记录保持者74%，而且还不是全能力运行。
田纳西大学的唐加拉教授帮助编排全球超级计算机500强排行榜，他披露了这些数据，介绍了这台计算机的Linpack测试速度。
According to Ars Technica, the fastest result was achieved using 90 per cent of the machine capacity. The stats come from a five-hour Linpack test using 14,336 nodes and 50 GB of memory of each node.
The test results place the Tianhe-2 ahead of the world’s current title holder, which is the Cray XK7 system-based Titan at the Oak Ridge National Laboratory in the US.
Scheduled to be installed at the National Supercomputer Center in Guangzhou before the end of this year, Tianhe-2 is being assembled and tested at China’s National University for Defense Technology (NUDT). Once operational, Tianhe-2 “will provide an open platform for research and education and provide high performance computing service for southern China,” Dongarra wrote, according to Ars Technica.
该杂志称，这个速度最快的结果是在机器动用90%能力的情况下取得的，经过5小时的Linpack测试，使用了14336个节点，每个节点50G内存。
这一测试结果使天河2号取代目前世界记录持有者——美国橡树岭国家实验室一台基于Cray XK7系统的“泰坦”(Titan)计算机。
天河2号计划安装在广州国家超级计算机中心，目前正在中国国防科技大学组装和测试。该杂志引述唐加拉的话称，一旦投入运行，天河2号将为研究和教育提供一个公开平台，为中国南方提供高性能的计算服务。
Does that mean China will nudge Titan off the top of the Top500 list? Time will tell. Interested watchers await June 17, when the latest rankings will be issued as part of the twice-yearly Top500 list. As the official record, that list is updated twice a year with the next list due out on the 17th.
Tianhe-2 has a theoretical peak performance of 54.9 petaflops. Measurements for the Top 500 list always fall somewhat short of theoretical peaks, but Tianhe-2 could certainly improve on its score of 30.65 petaflops if it ran Linpack across the entire system.
Tianhe-2 is the follow-up to Tianhe-1, which was #1 in the world in November 2010 and ranked eighth in the most recent list, with a speed of 2.57 petaflops.
这是否意味着中国将把泰坦从全球超级计算机500强榜首的位置挤出去？时间会证明的。感兴趣的观察人士要等到6月17日才能知晓，到时一年排两次的全球超级计算机500强排行榜将发布。从官方记录可以看出，榜单一年更新两次，下一次更新是6月17日。
天河2号的理论峰值是54.9千万亿次。500强的测试结果多少会比理论峰值低些，但如果整个系统全力运行Linpack测试，天河2号的表现肯定要比30.65千万亿次的这一成绩要更好。
天河2号是天河1号计算机的后续版本，后者于2010年11月夺得世界第一，在最新的排行榜中排第8名，运算速度为2.57千万亿次。

People questioning India’s capabilities in this field must know that our Param Yuva 2 supercomputer is the 62nd fastest supercomputer in the world. In terms of efficiency, it ranks 33nd in the World. It performs at a peak of 524 teraflops. Except for France, all the countries in Europe have supercomputers with much lesser processing speed. So we’re doing pretty well for a $2 trillion economy. As our economy grows our capability will grow as well.
Agree (7)Disagree (6)Recommend (4)
那些质疑印度在该领域能力的人必须知道印度Param Yuva 2超级计算机的速度排名世界第62，效率排名第33，峰值速度每秒524万亿次浮点运算。除了法国，欧洲各国超级计算机的处理速度要慢得多。所以对于一个2万亿美元的经济体来说，我们已经做得相当不错了。随着我们经济的发展，我们的能力也会提高。

纯粹是中国的犹太朋友捏造的垃圾新闻。中国根本没有类似日本或德国的先进计算机工业，它是一个非常原始落后的国家，从以色列获得美国的零件，然后精心制造这么一出过时的新闻。

Indeed this is the older U.S. technology given by Israel to China and set up by Jewish technicians. This computer is huge. Research things before you believe data coming from outside.

中国“天河二号”成为全球最快超级计算机收藏
17日公布的全球超级计算机500强排行榜中，。中国“天河二号”成为全球最快超级计算机
中国国防科学技术大学研制的“天河二号”以每秒33.86千万亿次的浮点运算速度，成为全球最快的超级计算机。 天河2号计划今年年底入驻广州的国家超级计算机中心，天河2号的组装和测试主要由中国国防科技大学（NUDT）承担。一旦验收通过，天河2号将对外开放平台，用于实验和教育领域。　　天河2号使用Intel Ivy Bridge和Xeon Phi 处理器，「32,000颗Ivy Bridge的Xeon和48,000颗的Xeon Phi共计2,120,000个内核。」Dongarra写道。天河2拥有12.4PB的硬盘和1.4PB的内存。NUDT采用自己的分布式计算技术，Dongarra描述为：「光电混合传输技术（optoelectronics hybrid transport technology），上层采用主干拓扑结构，通过13个路由，每个路由有576个端口连接。并运行麒麟LINUX系统。」转至：
