Resource Management Research Based On Grid Computing Environment

Resource management is one of the most important parts of grid computing. The validity and applicability of the grid resource management system depend on its scheduling strategy mostly. But the characteristics of grid such as high heterogeneity, adaptability, distribution and dynamic decided the complexity of grid resource scheduling. Therefore, the model of computer economic is used for resolving resource management and scheduling.Firstly, in this paper we introduce the concept, the characteristics, three development phases of grid, research at home and abroad, differences and relationship between grid computing and cloud computing.Secondly, we give a detailed account of Five-Level Sandglass Architecture and Open Grid Services Architecture.Thirdly, we introduce the relevant concepts of grid resource management, the three major grid resource management architecture and the typical grid resource management systems.Fourthly, we expound why introduce economics for grid resource management and introduce the economics based grid resource management system Nimrod-G, do simulated experiments on cost optimization, time optimization, cost time optimization, these three different deadlines and budget constraints (DBC) algorithm, and analyze experimental results.Fifthly, we apply the theory and the evaluation method of credit, combine with mature DBC algorithm, bring forward the DBC algorithm based on the credit, and implement the algorithm in order to solve the trust issue between resource consumers and producers in the resource scheduling process and to remedy the deficiency of the original algorithm.Sixthly, we introduce the reasons of using grid simulator for the experiment, the characteristics, architecture and the direction of use on the grid simulator GridSim. After the analysis the source code of the GridSim, combine with NetBeans IDE, data persistence framework iBATIS, MySQL database, we improve the source code of GridSim and provide additional function to support the GUI of grid simulation experiment and the operation of credit. Then we make simulation experiments on the DBC algorithm based on credit. Experimental results show that putting credit into the economic model is feasible, it increases the confidence between the grid resource consumers and producers, and improve the scheduling performance and resource utilization.Lastly, we conclude the paper and prospect a few directions for future research.
