From China's Tianhe second, the world's fastest supercomputer

When the TOP500 was released this year, from China's Tianhe second, the world's fastest supercomputer, powerful performance and independent technology shocked experts and scholars at home and abroad, they agreed: "Tianhe second Super computer system performance is shocking, China in the development of the independent control of the supercomputer to take another step." "Grounded application, leading innovation-2013 High Performance Computing User Conference", Lu Yutong, Director-General of Tianhe second, and professor of Defense science and technology will unveil the core technology of the world's fastest supercomputer.

"Grounding application, leading innovation-2013 high-performance Computing User Conference" is by the wave group United Tsinghua University, National Defense Science and Technology universities and other units jointly organized, aimed at promoting high-performance computing users of technical exchanges, experience sharing, promote the development of the application of the super.

Tianhe Second supercomputer is the world's first peak performance breakthrough 500 million times (50PFlops) supercomputer, compared to the previous ranking of the world's first U.S. "Titan" system, the footprint is its 85%, performance is its twice times. The new "Heterogeneous polymorphism" architecture is created by the super computer at Tianhe Second, it realizes the flexible configuration of multiple types of computing resources, input and output resources and service resources, adopts multi-level fault-tolerant design, the autonomous fault management technology of machine management machine and so on, and can more conveniently analyze, diagnose and deal with faults. , which indicates that China has mastered the world's leading system architecture and job scheduling management and other core technologies. In addition, Tianhe second, a number of innovative technology to achieve the world's leading level, for example, based on the independent communication interface chip and the interconnection Exchange chip design realizes the photoelectric hybrid independent custom high speed interconnection system, its performance is the current international most advanced commercial interconnection system twice times; using the integrated energy control mechanism, Energy efficiency than into the international advanced ranks; The design realizes the high density high-precision assembling structure based on the back-panel and the horizontal blind interpolation, and makes the calculation density of Tianhe second at the international leading level.

In this 2013 High-performance Computing user Conference, Professor Lu Yutong will not only fully reveal the second super computer above the excellent scientific and technological innovation strength, detailed analysis of these scientific and technological innovation behind the development case, but also to everyone concerned about China's independent scientific and technological innovation for all-round disclosure.
