Design and Implementation of a 3A Accessing Paradigm Supported Grid Application and Programming Environment

摘要

The mobile grid users accessing to grid services has become a normally paradigm for getting grid resources. To improve their working productivity in dynamic and open grid environment it should provide the mobile grid users an access-point decoupled and access-time decoupled way to access grid services. In development of the VEGA Grid, corresponding to the user accessing module in the Service-Oriented Architecture, we developed a kind of we called "3A(anytime, anywhere, and on any device) accessing paradigm" supported Grid Application and Programming Environment(GAPE). To the 3A accessing paradigm, we mean a mobile grid user not only could access grid services at anytime anywhere and on any device, but also could continuously manage the executing state of his grid applications even if he changed his access point or access time. This article analyzes the 3A accessing paradigm, and introduces the implementation of the VEGA GAPE.
