Abstract: High-performance computing (HPC) environment provides researchers with high level high-performance computing application services with unified access entrance, unified use method and user technical support through shielding the heterogeneity of job management system, access mode, management system and so on. With the development of the environment, more and more supercomputing centers, application communities, and service platforms are connected. Accounts of the supercomputing centers, communities, and service platforms are required to log in to the HPC environment using their original ways. The existing high-performance computing environment supports only grid accounts authenticated by LDAP (lightweight directory access protocol). Application communities and service platforms have their own users and different authentication modes. In order to provide a unified authentication center for the environment, this paper studies the multi-source account authentication technology and develops the multi-source user authentication system. At present, the HPC environment has supported multiple super computing centers. The major communities and platforms in the “high-performance computing” special project also have realized the connection with the national HPC environment through the multi-source account authentication technology. After the connection, accounts of the communities and platforms can log in with the environment grid accounts, at the same time use relevant resources.
