中國超級電腦全球第二強

Peter, I post this one on your behalf.  

中國超級電腦全球第二強
(明報)2010年6月1日 星期二 08:00

國際超級電腦大會公布500強超級電腦名單,中國的「星雲」系統超越眾多歐日超級電腦,躍居全球第二位。

位於深圳    的國家超級計算中心、由曙光公司開發的「星雲」(Nebulae)系統,運算速度達到1.27petaflops,一個petaflops相當於每秒可進行1000萬億次數學運算。

這個排行榜每半年發表一次。除了「星雲」外,中國國防科技大學    研製的「天河一號」亦排名第7,這也是中國首次有2部超級電腦,躋身前10強行列。

世界最快的電腦,仍然是美國    田納西州橡樹嶺國家實驗室的「美洲豹」(Cray Jaguar)超級電腦,該系統主要用於模擬核試驗等,去年11月該電腦在測試中取得了1.75petaflops的運算分數。

《紐約    時報》撰文稱,「星雲」一舉超過了眾多歐洲和日本    的系統,凸顯了中國在科技領域日益增長的實力和雄心。

美國在榜單中仍具有統治性的地位,既是生產最多超級電腦的國家,也是安裝利用最多的國家。

今年的500強超級電腦中,美國共佔了282台,較去年11月的277台有所提高。

不過中國很明顯有在這方面挑戰美國的雄心。曙光的「星雲」使用的是英特爾    和英偉達的芯片。但使用中國自行研發生產芯片的新系統,預期將於今年稍晚些時候問世。一些科學家和工程師表示,該系統可能奪得世界第一稱號。

美國勞倫斯伯克利實驗室的科學家西蒙指出:「唯一清楚的發展是,中國人正在挑戰最高端的超級電腦。」

田納西大學電腦科學家唐加拉表示:「到今年年底,中國的超級電腦運算能力,可能超過歐盟    各國的綜合,而且其系統可能奪得500強的榜首位置,為此我不會感到吃驚。」

你哋兩位媚共份子鍾意自我感覺良好嘅話,我當然唔會阻你。但作為一個電腦人,我就會話,以今時今日嘅電腦科技來講,超唔超級電腦其實真係無乜意義。

The thing is, with the advent of computer networks and distributed computing, many of the most complicated tasks are tackled not by a single supercomputer, but rather are discretized and the work spread out to be done by slower, but much, much, much cheaper systems and processor in parallel.  Doing things this way is far more cost-effective and efficient, and the scalability/flexibility is huge.

So in a sense, China pooling its resource to do something like this hardly surprises me b/c it  can be viewed as yet another 面子工程. What's the point of building one, or even a handful of luxury palaces, when the peasants and common person are still living it mud huts?

Mr Lik, your comments is flawed as usual. You are just jealous of Chinese progress. On the surface, you are just attacking the CCP, which is understandable, but in fact you are a racist against the Chinese. To morons like you, every thing that Chinese people do is for face only.

It is important that China improves the living standards of the people and their scientific technology level at the same time. They are not mutually exclusive.

Your comments on "distributed computing" is totally laughable. If you know nothing about supercomputing, then just STFU rather than embarrassing yourself yet again. All the other countries are still building supercomputers, the US, Japan, Europe are all building more new supercomputers. Why else would they do it if there is no such need? This shows there is a need for these computers, unlike what you claimed.

While "distributed computing" is another way of doing it, but you are still distributing work among very power computers. According to the experts the costs are about the same, unlike what you claimed. You still need about the same number of microprocessors to produce about the same amount of computer power, whether they are located at the same location or distributed across disparate locations.

In the US, there are so many universities, government and research labs that have supercomputers. There are so many scientific applications for supercomputers.
All these supercomputers are already cooperating with each other by distributing work among themselves. These computer are getting cheaper to build all the time. Today's supercomputer will look slow compared with the supercomputers 5yrs or 10 yrs from now.

Lik, we talking about government and universities doing advanced scientific research here, not your computer at home running SETI or Prime95 while idling.

哦? 你係電腦專才? 失覺曬。

As usually expected again, you will 將所有關於中國的事情都要上升到意識形態的層次. I can certainly find 當年紅衛兵打倒一切的精神的影子 on you. It certainly will raise doubts on what you said and your judgements on any issue relating to China and Hong Kong.

First, what is wrong with the technology achievements that China has made? It is just a piece of news about technologies. Why did you have to always turn everything into a political issue?

Second, just ask yourself. Is it your true believe or just to 為反對而反對 when you said supercomputers – “超唔超級電腦其實真係無乜意義”. The reasons you gave are very soft and cannot stand challenges at all. Do you mind to tell us what your specialty is in the field of computing?
