Tsinghua University's Department of Computer Science and Technology has once again clinched the top spot in the IO500 world ranking on supercomputing storage, as announced at the International Supercomputing Conference (ISC24) on May 15. The department's Storage Research Group is recognized for its application of the SuperFS file system on the "Pengcheng Cloudbrain-II," which led to their repeated success on the IO500 list.

The achievement is attributed to the outstanding work of the core team members, including Associate Professor Youyou Lu, Professor Jiwu Shu, and doctoral students Shaoxun Zeng, Hao Guo, and Yitian Yang. Their contributions were complemented by the guidance and support of Academician Weimin Zheng and Professor Wenguang Chen, along with the Pengcheng Laboratory.

The IO500 stands as a globally recognized benchmark for storage system performance in the field of high-performance computing (HPC). Esteemed as one of the premier indices within the HPC community, it underscores the critical importance of computational prowess, and efficiency of storage access and data transfer mechanisms. Since its establishment in November 2017, the IO500 list has been unveiled annually at leading HPC conferences, namely SC in the United States and the ISC Conference in Europe, reflecting the latest advancements in supercomputing storage solutions.
