With the development of innovative computing power and the new generation of artificial intelligence technology, the integration of supercomputing and artificial intelligence has become a key force driving scientific and technological innovation, and will provide a core driving force for the transformation and upgrading of various industries and the development of digital economy in our country for a long time. The 2023 Supercomputing Innovation and Application Conference, hosted by the National Supercomputing Center of Sun Yat-sen University in Guangzhou, brought together more than 400 representatives from national supercomputing centers, university institutes, and technology enterprises to share the latest achievements and experiences in the application of supercomputing empowered industries, and jointly explore the integration and development of advanced technologies such as supercomputing, smart computing, artificial intelligence, and big data. Takamatsu, an academician of the Chinese Academy of Sciences and President of Sun Yat-sen University, said that the development project of the new generation of domestic general-purpose supercomputing system of the supercomputing center has achieved phased results, which effectively ensures that the service capabilities of the center system continue to be leading at home and abroad. In the next step, Sun Yat-sen University will continue to support the construction and development of the center.It is hoped that the supercomputing center will continue to target the world’s cutting-edge science and technology and the country’s major strategic needs, actively connect with the local industrial layout, deepen the deep integration and intersection of multiple disciplines, and continuously produce major landmark application results to support the country’s high-level scientific and technological self-reliance. The Guangzhou Supercomputing Center has become the benchmark of our country’s supercomputing center "Tianhe-2". It was successfully developed in 2013 and won the TOP500 world supercomputing six consecutive championships, which is an important symbol of our country’s supercomputing system development entering the world’s leading ranks. Liao Xiangke, academician of the Chinese Academy of Engineering and chief designer of the "Tianhe-2" development project, pointed out that the application of domestic supercomputing has always been a major challenge for the development of supercomputing in our country. The National Supercomputing Center Guangzhou has established a first-class talent team, developed a series of field-oriented supercomputing application platforms, and independently developed the "Starlight" domestic multi-mode supercomputing integration application support platform to build a bridge between domestic supercomputing systems and supercomputing applications in various fields. "Guangzhou Supercomputing insists on building a world-class supercomputing center as its goal, constantly expands the supercomputing application field, independently develops core application technologies, and creates a field-oriented application service platform." Lu Yutong, director of the National Supercomputing Center Guangzhou, said that the number of users of the Guangzhou Supercomputing Center has increased exponentially from the initial more than 300 to more than 300,000. The independently developed Starlight Supercomputing application support platform won the Guangdong Provincial Science and Technology Progress Special Award. In order to further support the construction of the Guangdong-Hong Kong-Macao Greater Bay Area International Science and Technology Innovation Center, the center has built 15 sub-centers in the Guangdong-Hong Kong-Macao Greater Bay Area and established the Guangdong-Hong Kong-Macao Supercomputing Alliance, forming an application pattern based on the Bay Area, serving the whole country, and affecting the world. It has become the benchmark of our country’s supercomputing centers and ranks among the top five most influential in the world. Application case, in the Huo Yingdong Research Institute of the Hong Kong University of Science and Technology, the 100M network special line extending from the Nansha branch of the National Supercomputing Center of the Guangzhou Center is connected to the National Supercomputing Center in Guangzhou University Town in the north, and the Qingshuiwan Campus of the Hong Kong University of Science and Technology in the south, which closely connects Guangzhou Supercomputing with Hong Kong’s science and technology innovation, making it a "transfer station" for Guangzhou-Hong Kong science and technology innovation Gao Min, dean of the Huo Yingdong Research Institute of the Hong Kong University of Science and Technology, said that supercomputing has a strong supporting role for scientific research. Hong Kong has many famous universities and a large number of cutting-edge scientific research talent teams, and the demand for supercomputing is very strong. In recent years, the Hong Kong scientific research team has used Guangzhou supercomputing to bear fruit.The University of Hong Kong has developed the world’s most durable hydrogen fuel cell. Thanks to the "Tianhe-2", a team led by Shaw Man-wah, a professor of chemical and biological engineering at the Hong Kong University of Science and Technology and dean of the HKUST Energy Research Institute, has developed a new hydrogen fuel cell, setting a world record for the durability of the battery to generate electricity. Hydrogen fuel cells are less harmful to the environment, but they have never been commercialized on a large scale. The reason is that hydrogen fuel cells rely on electrocatalysts to generate electricity, but catalysts are generally made of platinum (Pt), which is not only expensive but also rare. Scientists have been trying to find more common and inexpensive substances such as iron-nitrogen-carbon as alternatives to platinum, but these substances have poor catalytic power generation efficiency and durability. Relying on the rich storage resources and powerful computing power of "Tianhe-2", the team simulated the oxygen reduction reaction (ORR) on the surface of the new mixed catalyst, used density functional theory (DFT) to prove that its catalytic performance is superior to platinum, and finally developed a new hydrogen fuel cell, which greatly reduced the amount of platinum required by the catalyst by 80%. This new mixed catalyst not only has extremely low platinum content, but its catalytic efficiency remains at 97% after 100,000 voltage cycles of accelerated stress testing. The research team of Professor Zhang Xin of the Hong Kong University of Science and Technology and the Hong Kong Institute of Sport collaborated to study the aerodynamic characteristics of the cycling process using advanced computational fluid dynamics (CFD) methods through the "Tianhe-2" supercomputer. In the calculation, the overall wind resistance was evaluated and optimized based on factors such as wind speed, cycling attitude, bicycle parts, and wheel rotation, and validated and supplemented with the wind tunnel experimental measurements, which effectively promoted the athlete’s posture optimization, equipment design, and selection process. The simulation calculation also provided the flow field distribution of different parts of the body, assisted in clothing design and material selection, and was combined with the wind tunnel experiment. As a result, Hong Kong cyclist Li Huishi improved her training efficiency and competition results, and won a valuable bronze medal in the women’s track cycling competition at the Tokyo Olympic Games.
