A Resource Representing Framework Enabling Dynamic Resource Discovery and Access Optimization

In domains of scientific and engineering computation, many applications share the characteristic that a large amount of batch jobs are included in the problem domain and these jobs can be executed concurrently on distributed resources. A register-based resource representing framework has been devised to allow these applications to be developed and executed independent of any specific resources, while providing them with the vital mechanisms to improve performance and reduce cost. The major strategies include enabling simultaneous accesses to distributed resources, enabling dynamic resource discovery for every jobs, enabling up to thousands of jobs to be submitted in one request, and utilizing every resource´s inner parallel computability. A set of tools for developing register-based resource representing frameworks have been implemented. And the promised mechanisms have been evaluated with the application gSVAP running on Peking University Grid.
