Research And Realization On Integrate Technology Of Simulation Resouce Based On Grid

With the appearance of DIS and HLA, computer simulation grows from single simulation systems to synthetically and network distributed simulation environment. Almost all simulation systems bring heterogeneity in computer hardware and interface,DBMS,network OS,development tools etc,makes the difficulties in resource sharing of all interactive simulation systems.The integrate of simulation resource based on Grid is an innovative theory and technology architecture changing the design and application patterns of DIS. It provides simulation resource users with the feasible idea and solution to capture; access,share,analyze,and process simulation data for simulation application requirements.Aiming at the requirements of data integration in the Simulation systems, this paper researches and analyzes the architecture and inner process of Globus and OGSA-DAI, proposes a design scheme of data integration platform based on Grid Service technology which resolves the problem of dynamic integration of heterogeneous databases.With the development of XML technology,Grid service technology,database integration technology, this paper mainly discusses the design and implementation for the data integration platform for the simulation database.We provide services for different nodes of simulation data through standard grid service interfaces and use XML to eliminate heterogeneity of data model from various systems.At last this paper gives the tests and results for this integration platform and analyzes the characteristic of this platform with a simulation application examples.
