On November 20th, the 44th World Supercomputer Top 500 list was announced. The “Tianhe No. 2†supercomputer developed by China National Defense University of Science and Technology once again topped the list. This is the fourth time since the first time in June 2013 that “Tianhe No. 2†has won the world's fastest laurels, once again guiding the world's attention to this supercomputer from China. With the development of economy and society, there are a series of complex and large-scale challenging problems in the fields of science and technology, economy and social development. To solve these problems, we must rely on super-fast computers with super-fast and large capacity. As a national 863 program and a “nuclear high-base†national science and technology major special project, “Tianhe No.2†is undoubtedly an important basic tool for national scientific research with its huge storage capacity and unimaginable calculation speed. It plays in many fields. Play an important role. Make cutting-edge technology effective and practical In November 2013, “Tianhe No.2†was put into operation at the National Supercomputing Guangzhou Center and officially opened to users at home and abroad. At present, the first phase of the upgrade of the second phase of the “Tianhe No. 2†is basically completed, the communication speed between the machines has doubled, and the released computing resource utilization rate is 76%. Experts predict that the computing resources of "Tianhe No. 2" will be released before the end of December this year. Next year, the Supercomputer Center will upgrade the Accelerator Card for "Tianhe No. 2" to improve the performance of its central processing unit. "Supercomputer development is difficult, it is more difficult to use. But we must not only develop the world's highest performance supercomputer, but also to develop a stable, reliable, widely used supercomputer, which is the goal we have always pursued." Filed "Tianhe II" Researcher Zhu Xiaoqian, deputy chief designer of the project, said. In order to make "Tianhe No.2" practical and easy to use, "Tianhe People" creatively proposed a heterogeneous polymorphic system structure according to the urgent need for the application of big data processing and smart city construction in China, especially in Guangdong Province and the Pearl River Delta region. A balanced design of the system is achieved. In response to the difficulty of using new architectures, they also developed a new programming framework to "mask" heterogeneous features. That is to say, when users use "Tianhe No.2", they can not only exert its powerful computing power, but also increase the difficulty of programming due to the complexity of heterogeneous polymorphic architecture, thus effectively improving the usability. Yuan Xuefeng, director of the National Supercomputing Guangzhou Center, said that in recent years, the demand for supercomputers in China has been growing steadily, and the innovative activities in various industries have provided a strong driving force for the rapid development of supercomputer development and application in China, and at the same time promoted technological innovation. Industrial upgrading, economic and social development. After the successful development of “Tianhe No.2â€, trial calculations have been started for several typical applications, and higher calculation efficiency and better calculation results than “Tianhe No.1†have been achieved. Researcher Lu Zexin, head of the pilot system technology at the center, said that "Tianhe No. 2" greatly exceeded the "Tianhe No. 1" in terms of calculation scale, calculation fineness and computational efficiency. Taking the genome-wide information correlation analysis of 500 people as an example, it takes only one year for Huada Gene to use its own computer system, and it takes only three hours to use Tianhe No.2. In the development of new cars, traditional design methods are used. After hundreds of real collision experiments, it takes more than two years to complete the structural design of a new car. The use of “Tianhe No.2†for vehicle crash simulation and aerodynamic simulation As a result, only 3 to 5 real vehicle collisions can be completed in two months. Technology "welfare" extends across all industries At present, “Tianhe No.2†has built materials science and engineering calculation, bio-computing and personalized medicine, digital design and equipment manufacturing, digital design of energy and related technologies, earth science and environmental engineering calculation, smart city and big data processing. Wait for six application service platforms. It has provided computing services to more than 250 users, and its application industry covers life, energy, and the universe. In the minds of "Tianhe people", "Tianhe No. 2" is a vast god, and it is omnipotent - China Commercial Aircraft Beijing Civil Aircraft Technology Research Center uses “Tianhe No.2†to carry out the full-parameter aerodynamic optimization design calculation of the large passenger aircraft C919. It only takes 6 days to complete the calculation amount that took 2 years to complete, which greatly improves the work efficiency. At the same time, for the first time, the high-precision large-scale numerical simulation of the complex configuration of the whole machine in the world was realized. The Shanghai Institute of Materia Medica of the Chinese Academy of Sciences conducted an evaluation of the binding affinities of 750,000 small molecule compounds based on “Tianhe No. 2â€, and completed the evaluation of in vivo and in vitro activities of more than 600 drugs, providing treatment for malignant tumors, hepatitis B, diabetes and other diseases. A new way. Shaanxi High Performance Research Center relied on “Tianhe No.2†to carry out quantitative research on financial risk based on Monte Carlo simulation method, and used 3344 heterogeneous computing nodes to conduct VaR simulation test, realizing multi-dimensional market risk of tens of millions of investment portfolios. Minute-level quasi-real-time measurement has laid a good foundation for computational technology to enhance the risk sensitivity of China's financial institutions, reduce risk-weighted assets, and improve the refined management of funds. At the same time, Tianhe No. 2 also adapts to key business systems such as Guangzhou e-government data management system and cloud disk storage system, and builds an efficient and reliable carrying platform for Guangzhou e-government and smart city construction. In April 2012, the National Supercomputing Tianjin Center and Tianjin University, and the research institutions of the five countries of the United Kingdom, Norway, Spain, Bulgaria and Switzerland applied for the China-Europe supercomputing strategic cooperation project based on “Tianhe No.1â€. Today, Tianhe II continues to provide high-performance computing services to foreign research institutions. The cooperation team of Munich University of Technology in Germany used the real earthquake seismic propagation simulation carried out by “Tianhe No.2†to simulate and reproduce the seismic wave propagation process of the 1992 Landes earthquake in California, providing a study on the propagation mechanism and earthquake prediction of seismic waves. New approach. It can be said that regardless of the scope, degree and efficiency, the application of "Tianhe No. 2" has been fruitful, bringing high-tech "welfare" to all walks of life. Sharing of scientific and technological resources benefits the people's livelihood Although "Tianhe No. 2" has made great achievements in a series of large-scale projects such as gene sequencing, biomedicine, pollution control, high-speed train design and manufacturing, but in Yuan Xuefeng's view, "Tianhe No. 2" can not only complete these "national name" The big project can also assist small businesses and help ordinary people realize their dreams. "This 'high on the ' is economical and practical, and ordinary people in need have the opportunity to experience a super-computing feeling." He said that through super-calculation technology, not only can an animation rendering platform be used to complete an animation production, but also applications such as virtual fitting and simulation test driving can be developed. For example, a clothing store owner can design a virtual person image based on his or her own consumer group, allowing it to try on clothes for consumers to choose. Li Nan, deputy dean of the School of Computer Science, National University of Defense Technology, and Li Nan, deputy director of the Tianhe No. 2 project, said: "The presence of the super-computing center has a lot to do with the lives of ordinary people. For example, supercomputers can greatly improve the accuracy of weather forecasts. In the entertainment industry, more than two-thirds of the characters and scenes in the movie "Avatar" are calculated by supercomputers." At present, "Tianhe No. 2" has provided computing services to more than 250 users, providing a free trial period of 50,000 core hours for each user, and preparing training classrooms for individual users. As of October this year, the “Tianhe No. 2†cloud service application has also achieved initial results. There are more than 20 cloud platform users, providing users with high security level resource services, and has successively completed the Guangzhou Municipal Government website group and e-government. Applications such as data exchange platforms. At the same time, it provides a huge amount of computing resources for the animation industry, and is currently supporting the rendering services of multiple users such as Huaqiang, Aofei and Cool Card. In the future, we will rely on “Tianhe No. 2†to provide the necessary computing and storage resources for various education management systems. In addition, in order to further play the role of science popularization base and education platform, the National Supercomputing Guangzhou Center is working hard to build the “Tianhe No. 2 Science Exhibition Hallâ€, and will follow up on the website to open a special super-free video training class to popularize the calculation. By then, it will not only provide a platform for young people to better understand supercomputing science, but also enable the public to further deepen their knowledge of the supercomputer science. We have reason to believe that with the continuous expansion of the application field of “Tianhe No.2†and the continuous advancement of its open resources, it will become a powerful engine for promoting national scientific and technological innovation, serving the society and improving people's livelihood.
