當臺灣人還在討論怎么在引入中資的同時保留自己的“核心技術”不給大陸時，
有了這么一條新聞

國際TOP500組織今天公布了最新一期世界超算性能榜單，中國再次登頂，包攬一二名。


榜單顯示，中國自主研制的“神威太湖之光”超級計算機峰值性能達每秒12.5億億次，
成為世界首臺運行速度超10億億次的超級計算機，央視稱，它一分鐘計算能力相當于70
億人用計算器不間斷計算32年！

另據了解，“神威太湖之光”設計穩定運行的最大浮點運算速度每秒9.3億億次，比“天
河二號”快出兩倍，效率更是提高3倍，且功耗也從17808KW降低到15371KW。

最最振奮的是，TOP500組織稱，“神威太湖之光”使用的是中國自主知識產權的芯片，
而非來自Intel，令人震驚。

資料顯示，神威太湖之光”由國家并行計算機工程技術研究中心研制，安裝在國家超級
計算無錫中心。

本次排名前十的還有美國的“泰坦”與“紅杉”、日本的“京”、美國的“米拉”和“
三一”、瑞士的“代恩特峰”、德國的“花尾榛雞”和沙特阿拉伯的“沙欣II”。




"It’s not based on existing architecture. They built it themselves,"
said Jack Dongarra, a professor at the University of Tennessee and
creator of the measurement method used by TOP500. "This is a system
that has Chinese processors."

Sunway TaihuLight’s victory is a particular challenge to Intel’s dominance
in computer servers, where it currently controls about 96 percent of the
market. It announced a joint venture with a Chinese organization to domesticate some of its technology earlier this year.


We have a more detailed analysis on that trend in particular here, but needless to say, this new system is remarkable architecturally, particularly in t
erms of its floating point per watt capabilities—as well as politically, as
this marks yet another divergence from the standard American-driven X86 norm for other machines around the world.

The Sunway TaihuLight machine has a peak performance of 125.4 petaflops across 10,649,600 cores. It sports 1.31 petabytes of main memory. To put the pea
k performance figure in some context, recall that the current (by far top)
supercomputer until this announcement had been Tianhe-2 with 33.86 peak petaflop capability. One key difference, other than the clear peak potential, is
that TianhuLight came out of the gate with demonstrated high performance on
real-world applications, some of which are able to utilize over 8 million of
the machine’s 10 million-plus cores.
