Research On Grid Architecture And Resource Management Framework

The grid technology is a hot technique developed in recent years, which integrate worldwide Internet resource into a virtual supercomputer, accomplish compute resource, storage resource, data resource, information resource, and knowledge resource to full share in global. The research of grid architecture is the base of grid systems design. It should sign the components of grid system, illuminate the key parts, and describe the functions, the purposes, and the characteristics of these parts. The most important function of grid is assembling the distributed resources in some different areas. It is so pivotal that an effective resource management framework and mechanism should be designed.This paper firstly introduces the conception of grid, summarizes the recent development of grid in recent years, and expatiates the importance of the grid architecture and resource management framework in the study of grid. An appropriate model is crucial for managing the diverse resources in grid environment. Therefore, A Service-Agent grid resource management model based on economic mechanisms is proposed. It is based on Service-Agent, which combines the dynamic agent with loose coupling of service. The market economics mechanisms and trade theories such as resource discovery mechanism, resource allocation mechanism and Bargaining_Min_min based on bargaining mechanism, are also presented to achieve the optimal allocation of grid resources so that providers and consumers could maximize their own interests and try to reach the win-win objective in grid market. At last we simulate our algorithm with the aid of SimGrid toolkit and verify that our algorithm is reasonable and efficient.With regard to the problems in the research of grid architecture, corresponding kinds of structures are designed from three points of view, such as the grid resources use & function management, user-oriented operation and the grid characteristics. After all factors considered, the architecture reconstructed and a prototype based on SOA named 3-dimensional information grid architecture (3DIGA) is proposed. And then does the research for some essential technologies, such as grid service proxy, the resource integration pool, service factory and so on. Finally the 3-dimensional information grid architecture is applied to the Ocean Information Grid integrative system for practice.
