US media: China into the world's fastest super computer to break the American blockade
"Kamui Taihu" super computer (Germany Golem website)Reference news, June 21 US media said, with a domestic processor chip built to beat rival equipment in the world, China claims to occupy the operation status of the Palace of top leaders are supporting.
Speed of envy of the world
According to the United States, the Wall Street Journal website reported on June 20, a large machine of Wuxi scientific computers in the world rate of twice a year topped the Fortune 500 list. The performance of this machine is the rule in China the top has 3 years of another device twice, their speed is roughly United States 5 times of the fastest equipment, which now falls in the third.
Reports said the new machine name "shenwei Taihu". This is without the use of United States cases made out of computer semiconductor technology won the top spot for the first time.
After ranking first computers using Intel chips, because last year United States issue a ban, Intel chip that cannot be exported to China for system updates.
Reports that China to invest heavily in this area with a sign that is ranking number of machines in China surpassing the United States, China, 167, United States 165.
The two new cases highlights the United States is seen as scientific research and plays a decisive role in the field of science and technology for national defense's dominance has foundered. Both result in Germany today held at the Supercomputing Conference announced.
Over the years, Governments are using supercomputers for weather forecasting, oil exploration, as well as for civilian applications such as product design, also use the supercomputer to crack the password, to develop nuclear weapons.
United States Department of energy allocated $ 525 million for the United States national laboratory building 3 faster supercomputer.
United States Congress is about to be completed, log in to leader in 2023 to retake supercomputer.
However, jieke·tangjiala University of Tennessee computer scientist said that the United States first "Kamui Taihu light" level the computer will not be put into operation until 2018. Dongarra on this computer in China report scheduled for release today.
Deputy Director of the Lawrence Berkeley National Laboratory huosite·ximeng said that China "far ahead in this race." Lawrence Berkeley National Laboratory is a major supercomputer user, involved in the design speed 500 list.
Simon says: "shocking is that this machine, each part is made out of China. ”
Reported that the United States is starting in 2010 was worried about Chinese competition. At that time, one called "milky way, first" briefly took the top of the computer.
"Milky way first" successor "Tianhe second" in 2013, on top, through a series of formal calculations, its speed is approximately 340 million times per second.
Dongarra said, "power of Taihu Lake" in the same calculation method, speed up to 930 million times per second, peak speed to 1.254 billion times per second.
Break the United States blockade
Reports said that at present, given that China and the United States both of national security concerns, China has been trying to reduce the United States dependence on chips. Last year, the United States and China's Ministry of Commerce rejected Intel Corporation "Tianhe second" 4 centres relating to the export of chip application, on the grounds that those bodies and "nuclear explosive activities" are linked. China has denied the allegations, using chips made updates to the system.
"Kamui Taihu" development agency officials at the National Engineering Research Center for parallel computers on Dongarra said, this machine can be used for manufacturing, life sciences, computer-aided engineering, weather and Earth system models and so on.
"Kamui Taihu" processor from high performance IC Design Center in Shanghai, which is a State-owned company, founded in 2003, the company is also famous for 2011 da-Zhen "shenwei Blu-ray" computer chips.
Dongarra said, "power of Taihu Lake" is not only powerful, but very high energy efficiency, is a more significant achievement than ever before.
He said the nearly 41,000 computer chip-on-chip has 260 named "cores" small calculation engine--so developers to 10.65 million cores into the 40 Cabinet. By contrast, the United States fastest supercomputers only about 560,000 of nuclear.
Seattle computer-maker Cray company bide·Wen Garo said, this is an impressive computer. He said: "we both know, you want to build a huge, complicated computer is not a small project. ”
Reports that China has 6 Supercomputing Center, one located in the city of Wuxi, near Shanghai. Funding for the Center comes from the "863 Program", which is the Central Government a plan for developing scientific and technological self-reliance, are considered vital to national security and economic development of the technology.
This computer's name next to a large freshwater lake in Wuxi. "Kamui" can be understood as the "power of God" or "magical powers".

美媒：中国超级计算机成全球最快 打破美技术封锁
“神威太湖之光”超级计算机（德国golem网站） 参考消息网6月21日报道 美媒称，凭借一台用国产处理器芯片建造出来的击败全世界对手的设备，中国号称占据运算顶级殿堂领头羊地位的说法得到佐证。
运算速度傲视全球
据美国《华尔街日报》网站6月20日报道，无锡的一台大型机器在世界科研用途计算机一年两度的速度500强排行榜中荣登榜首。这台机器的性能是中国统治该排行榜已有3年之久的另一台设备的两倍，其运算速度大致是美国最快设备的5倍，后者现在落在第三位。
报道称，这台新机器名叫“神威太湖之光”。这是中国在不使用美国半导体技术情况下制造出来的计算机首次夺得榜首位置。
此前排名第一的计算机使用的是英特尔的芯片，因为去年美国的一纸出口禁令，英特尔公司无法向中国出口用于系统更新的芯片。
报道称，能够表明中国对该领域进行重金投资的还有一个迹象，那就是中国上榜的机器数量首次超过美国，中国为167台，美国为165台。
这两个新情况凸显出美国在被视为对科研与国防具有决定性作用的科技领域的霸主地位江河日下。这两个结果定在德国今天举行的超级计算大会上宣布。
一直以来，各国政府不仅将超级计算机用于气候预测、石油勘探以及产品设计等民用用途，还用超级计算机破解密码、研制核武器。
美国能源部划拨了5.25亿美元用于美国国家实验室建造3台运算速度更快的超级计算机。
美国国会也快要完成立法工作，志在到2023年夺回超级计算机领域的领头羊位置。
不过，田纳西大学计算机科学家杰克·唐加拉说，美国第一台“神威太湖之光”级别的计算机要到2018年才能投入运行。唐加拉有关中国这台计算机的情况报告定于今天发布。
伯克利劳伦斯国家实验所副所长霍斯特·西蒙说，中国“在这一竞赛中遥遥领先”。伯克利劳伦斯国家实验所是超级计算机的一个主要用户，参与编制速度500强名单。
西蒙说：“这台机器让人震惊的地方在于，每个部件都是中国自己造出来的。”
报道称，美国是从2010年开始对中国的竞争感到担忧的。当时，一台名叫“天河一号”的计算机曾短暂问鼎该排行榜。
“天河一号”的后继产品“天河二号”在2013年成功问鼎，通过一系列正规测算，它的运算速度约为每秒3.4亿亿次。
唐加拉说，“神威太湖之光”按照同样的测算方法，速度达到每秒9.3亿亿次，峰值速度能够达到每秒12.54亿亿次。
打破美国技术封锁
报道称，当前，鉴于中国和美国两国都存在的国家安全疑虑，中国一直在设法减少对美国芯片的依赖度。去年，美国中国商务部否决了英特尔公司向与“天河二号”有关的4个中心出口芯片的申请，理由是这些机构与“核爆炸活动”有关联。中国否认了这些指控，改用国产芯片对系统进行更新。
“神威太湖之光”的研制机构国家并行计算机工程技术研究中心的官员对唐加拉说，这台机器有望用于制造业、生命科学、计算机辅助工程、天气预报及地球系统模型等领域。
“神威太湖之光”的处理器来自上海高性能集成电路设计中心，这是一家国营公司，2003年创建，该公司还为2011年声名大振的“神威蓝光”计算机制造芯片。
唐加拉说，“神威太湖之光”不仅性能强大，而且能效非常高，相比以往是一项意义更大的成就。
他说，该计算机有近4.1万个芯片——每个芯片上有260个名为“处理器核”的小型计算引擎——因此，开发者将1065万个核塞进了40个机柜。相比之下，美国速度最快的超级计算机只有约56万个核。
西雅图的计算机制造商克雷公司的总裁彼得·温加罗评价说，这是一台令人印象深刻的计算机。他说：“我们都明白，要建造一台这么庞大、这么复杂的计算机绝非一项小工程。”
报道称，中国有6个超级计算中心，其中一个就落户于无锡这座上海周边的城市。该中心的资金来自“863计划”，这是中央政府一项发展科技自足能力的计划，都是一些据认为对国家安全与经济发展至关重要的技术。
这台计算机的名字来自无锡旁边一个庞大的淡水湖。“神威”可以理解为“神的威力”或者“神奇的力量”。
