A Grid Resource Management Approach Based on P2P Technology

摘要

This paper presents a resource management approach in grid computing environment. Using P2P technology, this novel approach can manage dynamic grid computing resources efficiently. Different kinds of grid computing resources are organized into a P2P overlay network and available information is published in type of grid service. Task requests for computational resources are also presented as grid services. Problem of resources scheduling, is solved by services discovery. During the course of allocating computing resources to an application, task requests are forward in the P2P overlay network following the Chord routing protocol. With this approach, the computational resources of a grid system can be scheduled dynamically according to the real-time workload on each peer. Furthermore, the application of this approach is introduced into DDGRID, a grid system for drug discovery and design, to evaluate the performance. Solid experimental results show that computational resources of a grid system can be managed efficiently, and the system can hold a perfect load balance state and robustness.
