The successful construction of Jinan Center marks that China has become the third country to build a petascale supercomputer system with its own processor after the United States and Japan. Tested by the national authoritative organization, the continuous performance of Shenwei Blu-ray supercomputer system in Jinan Center is 0.796PFlops(PetaFlops, petaflops/second), the efficiency of LINPACK is 74.4%, and the performance-power ratio exceeds 74 1MFlops/W (petaflops/second watt).

Center positioning: public welfare high-performance computing technology and consulting service institutions.
Jinan National Supercomputing Center can analyze smog.
Although the smog problem still exists, the final result is not satisfactory, but in the face of smog, everyone should know a series of efforts behind it. Taking smog forecast as an example, today's technical level can accurately predict the air quality in the next three days or even longer. Dr. Tang Xiao, associate researcher of lasg State Key Laboratory of Atmospheric Boundary Layer Physics and Atmospheric Chemistry, said at the 20 15 Intel High Performance Computing Summit held recently that all kinds of early warning measures released at present are based on the judgment of air quality forecast.
Although it seems that the smog forecast may not be as mature as the weather forecast, what you may not know is the difficulty behind the smog forecast.
Tang Xiao believes that air pollution is a very complicated process. It depends not only on the weather but also on the chemical reaction process. For a simple example, the air pollution in China in the 1990s was called soot pollution, and now it is called compound pollution. At that time, when burning coal, the primary emission concentration of sulfur dioxide was very high, which was harmful but not easy to be observed by the naked eye. Now, you will obviously observe the influence of air pollution. The important reason is that primary pollutants are converted into fine particles, namely PM2.5, by chemical reaction, which has a great influence on atmospheric visibility. Tang Xiao said that there are interactions between chemical changes and meteorological processes.
Because many factors are involved, the final result is unpredictable. You have to analyze how many of these changes have occurred, how many have changed, and how many have spread with meteorological conditions ... This process requires huge computing power on the one hand and accurate computing models on the other. So far, in terms of institutional model, after years of exploration, China has built a model that conforms to China's national conditions. At the same time, China National Environmental Monitoring Center cooperated with Dawning and Intel several years ago to establish a high-performance computing platform for smog prediction and early warning.
It is estimated that no one dares to say that such a system can meet the demand. As Tang Xiao said in an interview, with the increasing demand for scientific research, they need more detailed monitoring, which means that more data will be generated eventually, and it will grow in the form of orders of magnitude; On the other hand, the calculation of chemical reaction with one emission is very demanding, because it is not one or two independent chemical reactions at all, but hundreds of chemical changes that may react with each other. This is a considerable demand for the final calculation.
In fact, the challenges faced by smog forecasting can be understood as the epitome of various application difficulties that require ultra-large-scale computing power. The demand space is still very large, but the current technical level is still very limited. For example, Iflytek once said in an interview that even the fastest supercomputers can't meet their actual needs in terms of computing power. So the next best thing is to think of some optimization and improvement measures besides computing power. This can be summed up as an important purpose of Intel High Performance Computing Summit, "to create a communication platform for everyone and share any good suggestions and practices."
In addition to smog, this conference also includes practice sharing in celestial observation, deep learning, marine climate and other fields ... Undoubtedly, high-performance computing is increasingly affecting all aspects of our lives, and the author sincerely hopes that technology can make our lives better. For example, on the smog problem, we can not only make predictions, but also give some more meaningful and easy-to-implement solutions for each region and even each factory. After all, economic development is still the top priority.
