Cross-domain data management for computing power networks

Cross-domain computing power networks wish to integrate computational and data resources from multiple computing centers, but existing methods do not pay enough attention to cross-domain file and data management.In this paper, a lightweight data access scheme for cross-domain computing power networks was proposed: (1) accessing parallel file system storage resources of remote computing centers through file system protocol conversion; (2) local caching as a supplement to cope with high IOPS applications; and (3) mounting remote or local storage to specified directories through container binding technology.The prototype system based on this scheme had been deployed on highperformance computing centers in multiple universities.The measured data and user experience showed that the scheme in this paper could meet the requirements of common high-performance computing applications.
