Service Oriented VEGA Grid System Software Design and Evaluation
Zha Li · Chinese Journal of Computers · 2005
Grid is open and distributed system, which has characters of scalability, dynamic and autonomy. To organize large scaled and disordered resources, providing share and coordination service are key issues that must be solved when constructing grid under Internet environment. VEGA research team aims at current shortages of grid platform, utilizes traditional computer system approach to study the grid and grid system software architecture. According to common requirements of grid application, this paper proposes service oriented and hierarchical grid system software architecture. The grid resource space concept is imported for grid resource virtualization, which can hide technological details for user when accessing them. Some key issues that grid system software needs to solve are introduced. Then the key technologies and design are discussed in detail to explain how we implement the VEGA grid system software. At the end of this paper, the authors analyze the system performance by batch job testing results, and evaluate the system from functionality viewpoint.
