Research On Resource Management In Grid Environment

It is very important to manage resources and schedule tasks in grid system effectively. The grid resources include many features such as distribution in wide area, heterogeneity, owned by different persons or organizations, different access and consume model, dynamic of balance, etc. Therefore, the resource management becomes increasingly complex.This paper talks about the requirements and functions of resource management in grid environment and present an abstract model about resource management. The main grid resource management systems are listed. Then, the computing economy model of resource management is introduced into the grid environment. We describe the advantages of using computing economy in the grid and present grid resource management theory model based computing economy.The introduction of the economic theory into the grid computing is a main contribution of this paper. The individual competition policy of the auction mechanism of grid resource was studied in this paper. The preference of user was presented by budget formula and utility function. At last, the model was proved as predict by grid simulation tool.
