The author:(作者)qqpublished in(发表于) 2013/11/21 1:34:46 Foreign Media： “the milky way， second，“ sit the world’s fastest computer Chair
The reference News November 20, entitled the foreign media: "the milky way, second" sit tight articles of the world's fastest computer Chair, main features are as follows:
"Tianhe second" super computer
Russia media reported that Chinese super computer "Tianhe second" again to create the world's fastest operation records. The latest global supercomputer in TOP500 organization pressed on the top 500 United States "Titans" won the Championship. Xinhua News Agency, reported on the 18th, "Tianhe second" 33.86 quadrillion calculations per second.
According to the ITAR-TASS agency reported on November 18, the supercomputer in China by the Chinese National University of Defense technology in Changsha, capital of Central Hunan Province development. United States, Tennessee, Oak Ridge National Laboratory developed a "Titan" second at 17.6 a quadrillion times per second speed.
Reported that in 2010, "Tianhe second" predecessors "milky way first," have the top ranking, but then Japan supercomputer "Jing" relegated to second place.
Reports that the TOP500 list of the global top 500 most powerful computer systems, began publishing in 1993.
According to United Kingdom the independent Web site reported on November 18, Chinese super computer remains the world's fastest supercomputer title, beating from Japan and the United States competitors.
Reports of "Tianhe second" floating point operation speed of supercomputers to 33.86 quadrillion times per second, this rate is almost a second name, the United States, "Titans" twice times the supercomputer, which floating point operation speed of 17.6 a quadrillion times per second.
World's fastest supercomputer rankings published every six months, last published in June 2013, the "milky way, second" at 33.86 quadrillion floating point operations per second speed to win for the first time.
Reports that despite China's supercomputer topped, but the United States still accounts for total dominance of lists, among the 500 top computer, United States 265. From the perspective of geographic dispersion, America ranks first, followed by Asia (115) and Europe (102).
However, computer scientists have criticised the way in which such tests, noting that flops alone does not directly represent the performance of supercomputers.
IBM Zurich research laboratory, head of computing science yalishandeluo·Ku Baglioni said: "we need more practical measures, on the basis of the most important applications of supercomputers to reflect their true purpose. ”
Baglioni stressed that although "Tianhe second" scored the highest marks in handling capabilities, but the efficient functioning of any computer problems. For example, although "Tianhe second" may be able to order specific high-speed processing data, but if it is unable to transmit data fast enough to the central processing unit, it may be unable to reach top speed.
However, the ranking of world's fastest supercomputers ranking way it's symbolically important means that any proposal that might be subjected to "resist".
《参考消息》11月20日发表了题为《外媒：“天河二号”稳坐世界最快计算机交椅》的文章，主要内容如下：
“天河二号”超级计算机
俄罗斯媒体称，中国超级计算机“天河二号”再度创造世界最快运算纪录。该机在国际TOP500组织最新全球超级计算机500强排行榜上力压美国的“泰坦”，夺得冠军。新华社18日报道，“天河二号”的运算速度达到每秒33.86千万亿次。
据俄塔社11月18日报道，中国的超级计算机由位于湖南省会长沙的中国国防科技大学研制。美国田纳西州橡树岭国家实验室研制的“泰坦”以每秒17.6千万亿次的速度屈居第二。
报道称，2010年，“天河二号”的前辈“天河一号”也曾登顶榜单，但随后被日本超级计算机“京”挤到第二位。
报道指出，TOP500是对全球500个最强计算机系统排名的榜单，于1993年开始发布。
另据英国《独立报》网站11月18日报道，中国超级计算机保持了世界最快超级计算机头衔，打败了来自日本和美国的竞争者。
报道称，“天河二号”超级计算机的浮点运算速度为每秒33.86千万亿次，这一速度几乎是第二名、美国“泰坦”超级计算机的两倍，后者的浮点运算速度为每秒17.6千万亿次。
世界最快超级计算机排名每半年公布一次，在2013年6月公布的上次排名中，“天河二号”曾以每秒33.86千万亿次的浮点运算速度首次夺冠。
报道指出，尽管中国超级计算机位居榜首，但美国仍占总榜单的主导地位，在500个上榜计算机中，美国占265个。从地理分布上看，美洲排第一，然后是亚洲(占115个)和欧洲(占102个)。
但是，计算机科学家们也对这种测试的方式提出了批评，指出单凭浮点运算次数并不能直接代表超级计算机的性能。
国际商用机器公司苏黎世研究实验室计算科学负责人亚历山德罗·库廖尼博士说：“我们需要更实际的衡量方式，在这些超级计算机最重要的应用基础上反映它们的真正用途。”
库廖尼强调，尽管“天河二号”在处理能力上得分最高，但任何计算机的有效运行都存在问题。例如，尽管“天河二号”也许能够以特定的高速处理数据，但如果它无法以足够快的速度将数据传送到中央处理器，它可能就无法达到最快速度。
但是，世界最快超级计算机排名的重要象征意义意味着任何改变排名方式的提议都可能会遭到“抵制”。
