中国称霸超级计算机排行榜 总体表现超越美国

Once again, China dominated a new list of the world's fastest supercomputers, not only taking the top two seats, but also pulling ahead of the US in the sheer number of systems being used.

中国再次在新一期全球最快超级计算机榜单上占据优势，不仅夺得榜单前两名，还在被使用系统的绝对数量上超越了美国。

According to a biannual ranking of the world's 500 fastest supercomputers, called the Top500, China's Sunway TaihuLight maintains the lead as the No 1 system for the fourth time, with a performance of 93.01 petaflops.

全球最快超算500强榜单Top500每年发布两次，根据日前发布的榜单，中国的“神威·太湖之光”以每秒93.01千万亿次的浮点运算速度第四次蝉联冠军。

China's Tianhe-2, or Milky Way-2, is still the No 2 system at 33.86 petaflops.

中国的“天河二号”以每秒33.86千万亿次的浮点运算速度蝉联亚军。

The No 3 is Switzerland's Piz Daint, which is also the most powerful supercomputer in Europe. A new system in Japan, called Gyoukou, is the No 4, pushing Titan, the top US system, to the No 5.

欧洲最强超算、瑞士的“代恩特峰”位居第三。日本新系统“晓光”超越美国最强系统“泰坦”位居第四，“泰坦”排名第五。

The 50th edition of Top500 ranking also shows that China has overtaken the US in the total number of ranked systems by a margin of 202 to 144.

第50期Top500还显示，中国的上榜超算总数超过了美国，中国为202台，美国为144台。

China has also overtaken the US in aggregate performance as well. The Asian country now claims 35.3% of the TOP500 flops, with the US at second place with 29.8%.

此外，中国还在整体表现方面超过了美国，占所有运算性能的35.3%，而美国占比为29.8%，位居第二。
