China’s High-Energy Photon Source (HEPS), the first national highenergy synchrotron radiation light source, is under design and construction. In the future, at the first stage of HEPS, it is predicted that 24PB raw experimental data will be produced per month from 14 beamlines. Faced with such a huge scale of scientific data and diverse data analysis environments in light source disciplines, the HEPS scientific computing platform was designed and implemented based on container mirroring and dynamic orchestration technology to provide HEPS users with a data analysis environment. In this article, a data security access strategy is designed and evaluated for a scientific computing platform to ensure the security and efficiency of data access for users in the entire process of data analysis. First, the general situation of HEPS is introduced. Second, the challenges faced by the HEPS scientific computing system. Third, the architecture and service process of the scientific computing platform are described from the perspective of IT, some key technical implementations will be introduced in detail. Finally, the application effect of data access security policies on computing platforms will be demonstrated. |
