Distributed Computing Status at IHEP, CAS

The Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences leads international collaborations on multiple large-scale experiments, which rely on grid computing to handle massive data across global sites. IHEP has deployed a robust computing infrastructure using systems like DIRAC and Rucio, along with custom-developed components for specific experimental requirements. This paper details the current state and architecture of IHEP’s distributed computing services and their role in enabling large-scale scientific collaborations in high-energy physics.
