Outline of Final Research Achievements

Toward the realization of parallel volunteer computing (VC) using personal computers (i.e. nodes) on the Internet, this research project studied the system configuration method. For realizing dependable parallel VC, we need to solve the two challenging problem: how to configure node groups for job assignment and how to cope with node defection for inter-node communication. We focus on the redundant computation which is widely employed in the current VC, and solve the two problems simultaneously by the approach of dynamically reconfiguring node groups. We implemented the prototype parallel VC system based on the approach and demonstrated the feasibility of dependable parallel VC.
