Research and Implementation of Distributed Simulation and Parallel Rendering System Based on Grid

With the development of Grid technology and the extension of Grid application areas, it needs to provide core infrastructure platform and the necessary functional components for large-scale resources sharing and collaboration. Based on the previous implementation of interactive Grid visualization system, this paper extends its runtime environment layer to provide Grid supports for the existing distributed simulation support platform and parallel graphics rendering system based on PC cluster, consequently realizes dynamic resource allocation and scheduling. Additionally, we present and implement a Grid-based distributed simulation and parallel rendering system which provides large-scale distributed simulation service and parallel rendering as well as high-resolution multi-screen tiled display service of massive complex scene to end users through an extended Grid portal.
