As a prevalent paradigm for flexible, scalable and on-demand provisions of computing services, Cloud Computing can be an alternative platform for scientific computing. In this paper, the authors propose an efficient resource management system for on-line virtual clusters provision, aiming to provide immediately-available virtual clusters for academic users. Particularly, they investigated two crucial problems: efficient VM image management and intelligent resource mapping, either of them has remarkable impact on the performance of the system. VM image management includes image preparation and local image management on physical resources.
