Research of Key Technology for Distributed Simulation Grid

Grid is a collection of sharing resources that perform tasks.It appears to users as a large system,providing a single point of access to powerful distributed resources.To meet the requirement in developing distributed simulation technology,it is necessary to introduce the grid technology into simulation and build a distributed simulation grid(DSG) platform.Based on the analysis of feature of grid and simulation system,the concept and technology frameworks of DSG were proposed.Furthermore,from the view of technical implementation,some key technologies were studied in building DSG platform.These technologies include:(1) unified user management,(2) resource management and scheduling,(3) job management and scheduling,(4) parallel and cluster RTI,and so on.A prototype of simulation grid was designed based on the key technologies of DSG.
