Research On Grid Resource Allocation Based On Competition Price Model

With the third tide of the Internet, application based on the technology have become a tendency of the resource share domains. Grid is not a new word for Internet, neither is it mean to abandon or replace Internet. The end-all of grid can supply the transpicuous computing abilities which have no concern with geographical location and specific computing facilities to common users. To provide the good grid QoS, the most important thing is to provide a good management method for grid resources. The scheduling of the resources is the key technology of the management of grid resources which is the core component of grid. It is the one of the pop and difficulty problems in grid computing research field. The efficiency of grid resource scheduling is important. It means that the scheduler must submit tasks to the suitable resources and reduce the leisure situation of resources.Based on the dynamic, heterogeneous and autonomous characteristics of resources in the grid environment, resource providers and resource consumers could compose a community like a real society. The price theory and a series of price strategies resulting from the practice are proved to be effective and persistent methods for resource management in the society. Therefore, it is necessary that economic theory should be introduced into the issue of resource management in the grid context. Correspondingly, a competition-price based grid resources allocation model was proposed in this paper, and the resource allocation policy was designed. The simulation experiment show that it can fit the dynamic changing better in the grid environment and dynamical adjust balance between supply and demand .At the same time, a new cost optimization algorithm was proposed in the paper.
