Abstract:
This paper investigates grid computing from the point of view three basic computing platforms. Each platform considered consists of virtual compute resources, a programming environment allowing for the development of grid applications, and a grid operating system to execute user programs and to make solving complex user problems easier. Three platforms are discussed: compute grid, metacompute grid and intergrid. Service protocol-oriented architectures are contrasted with service object-oriented architectures, then the current SORCER metacompute grid based on a service object-oriented architecture and a new metacomputing paradigm is described and analyzed. Finally, we explain how SORCER, with its core services and federated file system, can also be used as a traditional compute grid and an intergrid — a hybrid of compute and metacompute grids.
