Grid Resource Discovery Approach Based on Matchmaking Engine Overlay
Resources must be readily identified and accessed to execute jobs or run applications in grid environment. Traditional matchmaker framework performs to find matching resources in terms of resource requirements description, however adopted centralized model brings single point of failure in addition to performance bottleneck problem. P2P technology has been argued to have advantages in scalability and fault tolerance, nevertheless it is limited to support variable complex resource requirements to discover resources, mostly based on keyword or single attribute. In this paper, we propose a novel resource discovery model by organizing matchmaking engines into P2P overlay, which employs both matching technology and P2P technology, thus matching semantics and scalability can be achieved. Simulation results demonstrate that the proposed model is naturally appropriate to the organization-based nature of grid, capable of discovering matching resources efficiently and accurately.
