Abstract: The innate coarse-grained management of grid computing leads to inflexible structure, which brings about much inconvenience and inhibits a broader application of grid computing. With the virtual organization concept, this paper proposes a dynamic virtual organization management scheme which provides fine-grained project management to solve this problem. This scheme manages grid projects as different virtual organizations and controls user access according to membership relations in virtual organizations. Above the Globus grid system, the paper develops a dynamic virtual organization management system. It also gives a case to demonstrate the effectiveness of this scheme for fine-grained dynamic management of multiple grid systems.
