摘要
分布式仿真已经广泛应用于科学研究、工程、商业等方方面面。HLA的提出是为了解决分布式仿真中不同类型的仿真模型、仿真应用模块之间的互操作和提高仿真组件的重用性,并没有涉及到仿真资源层的管理,所以在面对现在分布式仿真向大规模发展和需要使用在地理位置上处于分布式的计算资源和数据资源时,存在一定的局限。基于网格的分布式仿真是一门刚刚起步的新兴技术,它致力于将传统的分布式仿真移植到网格环境中,以利用网格技术的各项优势。文中介绍了分布式仿真与网格技术的发展与应用现状,随后着重介绍基于网格的分布式仿真的研究发展前沿,并分析讨论了其面临的问题和发展的方向,为进一步的研究提供一定的指导性帮助。
Modeling and simulation permeate into all areas of business, science and engineering. The High Level Architecture （ HLA）, whose purpose is to facilitate interoperability among simulations and reuse the simulation components, does not deal with computing resources management. Therefore deficiencies associated with HLA appear when increasingly complex simulation systems often require huge computing resource and data sets that are geographically distributed. The computing grid - based distributed simulation is a new technology, which intends to run distributed simulation in grid environment to utilize the gird technology advantages. This paper gives an overview of development and present application of distributed simulation and Grid technology. Particular emphasis is placed on the present research situations of applying Gird technology to HLA - based distributed simulation, Subsequently the confronted problems and the development directions are analyzed for the future research.
