Key technologies of simulation grid resources pool

A simulation grid resource pool is the base for the grid-based simulation, and it completes simulation task by dynamically invoking simulation resources. To construct such a standard pool, the grid-enable technologies of simulation resource based on grid service were introduced. For assembly and collaboration of the resource, a Platform Independent Model (PIM) was adopted to describe simulation resource at conception level; the grid service was extended by adding simulation functionality, and the resulting service was called simulation service, which was compatible with High Level Architecture (HLA) and grid standard simultaneously. The specification of simulation service was put forward, including the structure, interfaces, service object model, and management mechanism. At development time, the PIM was parsed to generate simulation service code. The design of service code generator based on template was discussed and a resource pool was constructed based on above-mentioned specification and technologies. Finally, two applications were presented pool.
