U.S. research supercomputer is expected to overtake China by 2012

U.S. media recently revealed that the U.S. is developing the world’s fastest supercomputers, plans to launch in 2012, so beyond the current super computer “ringleader” – developed by China’s “Milky Way” . But public opinion pointed out that as China and Japan have continued to develop supercomputer, “the world’s fastest supercomputer,” which the top title in the U.S. wearing long not to say.
many arrows fly over to catch China
the U.S. Department of Energy’s Oak Ridge National Laboratory in 2012 launched the “Titan” super computer will exceed the China’s fastest computer “Milky Way.” “Titan” design speed will reach 200 million billion times per second floating-point operations, it needs work one day people use 120 billion 120 billion units calculator 50 years to complete. “Titan” cost a lot of money, expected to cost $ 100 million. The first phase of development will be completed by the end of this year, the second phase of research will end next year. “Titan” as the Department of Energy customization, will be mainly used to calculate the complex energy system, the United States.
According to the latest Top 500 supercomputer list, the Chinese National Defense University in October last year launched the “Milky Way” is the world’s fastest supercomputer, computing speed per second 2500000000000000 times. The United States will launch the “Titan” is a billion billion times the impact speed of operation. Some experts said the billion billion times more than a petaflop computing systems, powerful computing system 1000 times. Construction billion billion operations system is the demand of scientific development, will human health, biotechnology and many other areas have a tremendous impact on the world scientists are working to develop new architecture and programming model to support the billion billion operations system. Had previously been expected, based on processor technology, the first billion billion operations a second system may launch in 2018.
However, the “Titans” came out in 2012 may not be the only supercomputer in the United States. IBM Corporation in California, Lauren Oxley molar National Laboratory is also developing its own super computer. This machine, known as “Sequoia,” the computing speed of 200 million billion times, specializes simulate nuclear explosions, in order to reduce the social reality of the nuclear test. Lauren Oxley molar National Laboratory, said spokesman Don Johnson, the first of these two supercomputers is expected to be released in June 2012 Top 500 list of supercomputers appear.
IBM vice president responsible for calculating depth 戴维图瑞克 has pointed out that in the supercomputer field, China is accelerating the pace of the United States in the field of supercomputing leadership poses a threat. In addition to China, Japan and some European countries are catching up. Tu Ruike that in the year, China’s top 500 supercomputer list will be more than Europe combined. In the latest ranking of top 500 supercomputers, there are 41 sets of the system in Mainland China list, after the United States. Difficult to quickly enhance competition
U.S. media that China and Japan are also stepping up development of faster supercomputers, it can not be determined, etc. “Titan” and “Sequoia” come out of the can when the won the “World fastest “title. 500 units in the world’s fastest supercomputer system, the United States exclusive of 275, occupies a dominant position in this field. However, as countries are speeding up to build their own supercomputer, the field of global competition is becoming fierce.
Currently, Japan has built a more powerful supercomputer, a major project is called “K computer” system, the speed is expected to reach 100 million billion floating point operations. The super computer by Fujitsu for the Japanese Ministry of Education’s plans to build high-performance computing infrastructure, will be launched in 2012. But the U.S. supercomputer experts said that the biggest challenge facing the United States from China, not only is the “Milky Way”, and third-world performance of supercomputer system “Dawn Nebula” also belongs to China. “New York Times” reported that China is challenging U.S. dominance in this field. “Wall Street Journal,” said Chinese authorities have vowed to have at least five years after the performance of the system to reach 500 million million to 1 billion billion times the speed of operation.
the United States a little “bad money”
“The Wall Street Journal” said that China installed the world’s fastest supercomputer, the U.S. government agencies and businesses immediate action to restore America’s leadership in this technology. However, this challenge may be much more complex. The next step to achieve the computing performance of major catch-up, need to have as many as 10 million computers a system composed of a breakthrough in programming, this is a difficult task.
California Lawrence Berkeley National Laboratory is a major supercomputer users, Horst Simon, deputy director of the lab is not easy to admit to catch up. But he stressed that development of more powerful supercomputers to do my best, so if no new generation of super computer systems, some important scientific issues will not be resolved, it is an economic competitiveness, a national security issue. Oak Ridge National Laboratory, deputy director of 托马斯撒迦 Elijah estimates, development work over the next eight years, an additional 4 to 5 billion U.S. dollars of federal funds. Media that the current Republican Congress determined to reduce the deficit, to persuade them to provide subsidies for such research would be difficult. However, the fierce competitive situation helps countries to promote the U.S. government to increase investment. (Wang Shanshan)
