On June 1^st, the 24^thGraph 500 ranking was published at the High Performance Conference (HPC) held in Hamburg, Germany. The graph computer DepGraph, developed by a professional team from HUST, has broken the world record for graph processing performance again, and ranks first in the Graph 500 ranking. This achievement marks the first time that the graphing computing performance of a single machine has exceeded that of a supercomputer.

With the advent of the era in which big data and, global big data intertwines with each other, we are witnessing rapid development in this sector. As graphs could help us better understand the complex correlations in our world, its real life applications sprouts far and wide, such as Taobao user friend graphs, road maps, circuit diagrams, virus transmission networks, state grids, literature networks, social networks, and knowledge graphs.Thus, graph algorithms are also developed to obtain useful information from the correlations between these data. They gain important insights hidden in the graph data, such as importance ranking, shortest path, as well as connected components by iterative processing of the large graph data. Graph computing, as the core technology of the next generation of AI, has been widely applied in medical care, education, military affairs, finance, and others sectors. It has also been attracting a lot of attention from governments, global research and development institutions, and giant companies. It is becoming a new and relevant trend in the competition of global science and technology.

Graph 500 of the International Supercomputing Conference (ISC), jointly organized by ACM and IEEE, is the most authoritative list in evaluating graph computing performance. All the supercomputers in the world compete for a place on the Graph 500 list to testify to their superior computing power. Supported by the National Key Research and Development Program “the General Computer Technology and System for Graph Computing”, the team is guided by Associate Professor Zhang Yu and Dr. Zhao Jin from the National-Local Joint Engineering Laboratory for Big Data Technology and System, the Key Laboratory of Service Computing Technology and System under the Ministry of Education and the Key Laboratory of Cluster and Grid Computing of Hubei Province at HUST. Prior to this record-setting achievement, after years of research, the team has made breakthroughs in several key technologies in graph processing accelerators and graph computing system software. The graph computer DepGraph developed by this team ranks first in both the 18^thGreen Graph 500 and the 23^rdGraph 500 rankings.In the 24^thGraph 500 competition, DepGraphSupernode exceeded the performance of supercomputers including Fugaku from Japan, ranking first again.
