A new mechanism for resource monitoring in Grid computing

Grid computing is a technology for distributed computing. To manage a large scale of Grid resources for dynamic access, resource management is a key component. In this paper, a Grid Resource Information Monitoring (GRIM) prototype is introduced. To support the constantly changing resource states in the GRIM prototype, the push-based data delivery protocol named Grid Resource Information Retrieving (GRIR) is provided. There is a trade-off between information fidelity and updating transmission cost. The more frequent the reporting is, the more precise the information will be. But there will be more overheads. The offset. sensitive mechanism, the time-sensitive mechanism, and the hybrid mechanism in GRIR are used to achieve a high degree of data accuracy while decreasing the cost of updating messages. Experimental results show that the proposal alleviates both the update transmission cost and the loss of data accuracy compared to prior methods. (c) 2008 Elsevier B.V. All rights reserved.
