Sun Grid Engine(SGE)can be used to construct local and cluster grids.A recent research of building SGE-based distributed simulation grid framework was proposed,where simulation grid could execute HLA-based applications which were submitted to the grid by simulation users.Time management of simulation grid and task migration mechanism of simulation application were discussed.Further,checkpoint approach was adopted to implement the migration and dynamic scheduling of simulation task.The simulation grid framework supports the user-level and kernel-level checkpoint of simulation task.Specifically,the framework provides the dual channels of communication.Besides,the grid supports two modes of HLA scheduling tasks,which are differentiated according to processes and federates.Results of this study demonstrate the technical feasibility of constructing SGE-based simulation grid,and build a prototype system to execute HLA simulation tasks.
