Supercomputers are used to perform complex simulations or applications to help scientific research in a wide range of industries
China has almost tripled its number of supercomputers, according to a reputable list of the world's most powerful machines.

世界上最强大的电脑的名单中,中国入选的超级计算机数量增长了近两倍。


The country has 109 high-performance computing systems on the biannualTOP500 Listof supercomputers, up 196% from 37 just six months ago.

中国有109台高性能计算系统进入一年两次的超级计算机Top500的名单,与6个月前的37台相比增长了196%。

The most powerful supercomputer, China's Tianhe-2, also retained the top spot for the sixth consecutive time.

同时,超算第一名的中国天河二号保持了六连冠。
In contrast, the US has seen the number of its supercomputers decline.

相比之下,美国的超级计算机的数量出现下降。
The US has 200 machines in the rankings, which is the largest number from a single country. But, that total number has fallen to the lowest level since computer scientists started compiling the list 22 years ago.

排名中美国有200台入选,是入选最多的一个国家。但是,总数量已降至自1993年《计算机科学家》开始编制名单以来的历史最低水平。

Tianhe-2 was created by China's National University of Defense Technology and is being used at a supercomputer centre in the southern coastal city of Guangzhou.

“天河二号”由中国国防科技大学研制,位于南方沿海城市广州的超级计算机中心。
It is capable of performing 33.86 quadrillion calculations in one second, which is almost twice the speed of the second most powerful supercomputer on the list - the US energy department's Titan.

它能够执行每秒33.8千万亿次的浮点运算,其速度是排名第二的将近两倍,第二强的超算是来自美国能源部的“泰坦”。
Supercomputers are developed to perform complex simulations or applications to help scientific research in a wide range of industries such as predicting weather forecasts to making drug discoveries and DNA sequencing.

超级计算机用于开发执行复杂的模拟或应用程序,对科研等广泛领域大有益处,如预测天气预报,药物发现和DNA测序。

Rajnish Arora, vice president of enterprise computing at market research firm IDC Asia Pacific, said China's rise does not necessarily mean the US is under-investing, but is more to do with the evolution of China's economy and businesses.

Rajnish Arora认为中国超算的崛起并不意味着美国的在此领域的投资不足,而是中国经济与企业发展的结果。
"When China started off appearing on the centre stage of the global economy in the 80s and 90s, it was predominately a manufacturing hub," he told the BBC.

他告诉英国广播公司说:“当中国在80,90年代开始出现在全球经济的中心舞台时它主要是一个制造业中心。”
"All the IP (intellectual property) or design work would happen in Europe or the US and the companies would just send manufacturing or production jobs to China.
“所有的IP(知识产权)或设计工作都在欧洲或美国的公司,只是给中国制造或生产。
"Now as these companies become bigger, they want to invest in technical research capabilities, so that they can create a lot more innovation and do basic design and engineering work."

“现在随着这些公司变得更大,他们想要投资于技术研究领域,这样他们可以创建更多的创新,做基本设计和工程的工作。”
The Chinese government and companies want to become the creators and not just producer of products that are being designed elsewhere, he added.

而中国政府和企业都希望成为设计者,而不仅仅是生产在其他地方设计的产品,他补充道。
How valuable are supercomputers?
超级计算机有多珍贵?


In 1999 IMB announced a five-year $100m development project to build a supercomputer that would simulate the building of proteins in the body. It was called Blue Gene and in 2004 was the fastest computer in the world

David Schibeci at the Pawsey Supercomputing Centre in Western Australia said that while the Top500 list is a good "general rule of thumb", it is not the final arbiter of the value of supercomputing services.

来自位于西澳大利亚超级计算中心的David Schibeci说,虽然进入超级计算机Top500是一个很好的先决条件,但它并不是超算服务价值的最后仲裁者。
"I'd expect ranking systems to develop a focus on how much valuable research is produced by these systems and the outcomes that benefit the world," he said.

“我期待排名系统能够关注由这些系统开发出的造福世界有价值的研究和成果”,他说道 。
"Nations like China have a great opportunity to take a leading role in the HPC (high-performance computing) space but it's important that they focus on research support and upskilling of staff rather than just raw numbers for the Top 500."

“像中国这样的国家有一个很好的机会去做HPC(高性能计算)领域的主角,但重要的是他们要关注研究扶持和提升员工技能而不是仅仅挤进前500名。”

Chinese companies are also taking a lead as manufacturers of supercomputers, according to the Top500. Chinese firm Sugon overtook IBM in the systems category with 49, while IBM ranks fourth with 45 systems. US tech giant Hewlett-Packard is at the top of the list with 156 supercomputer systems.
根据TOP500,中国超算制造商公司也是超级计算机制造的领导者。中国公司Sugon(曙光)超越IBM有49台超算入选,而IBM入选45台,排名第四。美国科技巨头惠普(hewlettpackard)以156超级计算机系统入选,排名第一。
However, the rankings of the world's top five supercomputers has remained unchanged since June 2013. Mr Arora of IDC says this is in part to do with the significant investment required to build a supercomputer.

然而,排名世界前五名的超级计算机2013年6月以来一直保持不变。IDC的阿罗拉认为这主要是因为建造一台超级计算机需的大量投资。
"Companies need to assess whether they really need that large a system to solve the problems they have," he said.

他说。“公司需要评估他们是否真的需要那么强大的系统来解决面临的问题,”
The availability of money is driving Chinese investment in the industry, added Andreas Wicenec, professor of data intensive research at the University of Western Australia.

充足的资金是推动中国投资超算的动力,来自西澳大利亚大学的数据密集型研究教授Andreas Wicenec补充道,
"[It is] to show a high, almost disruptive impact in a field that was completely dominated by the US for decades," he said. "At this point in time, the impact of all these computers is not visible in research outputs in the fields I am used to monitoring more closely."

“(这)产生了非常显著的几乎是毁灭性的影响,这一领域几十年来几乎完全是由美国主导的,”他说。“在这个时间点上,在我观察的领域里,所有这些超算系统对研究成果的影响都还不明显”
However, if China opened its vast computer resources to international collaborators, its impact in the research field could change very fast, he added.

然而,如果中国开放其庞大的超算资源给国际合作者,其在研究领域的影响将显而易见,”他补充说。
