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 high-performance 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.
