【摘要】 针对仿真运行支撑环境的网格化问题进行了研究.摒弃单一运行时支撑环境(RTI)网格化研究模式,从多个RTI入手,研究RTI服务资源在广域网上的共享、协作与调度等问题;将多个RTI服务资源统一管理,形成RTI服务联邦,利用心跳机制保证每个RTI服务的有效性,同时设计专门的调度方式保证RTI服务负载能力.开发了一种基于网格联合仿真平台,理论分析和实际测试表明,本平台解决了单一RTI瓶颈问题,实现了RTI资源在广域网上共享,为进行大规模、多联邦复杂仿真系统提供了良好支持.更多还原

【Abstract】 The research of the distributional simulation run time infrastructure(RTI) based on grid technology is conducted.Abandoning the tradition research pattern to a single grid RTI,It aims at the multi-RTI,studies the online resource sharing,collaboration and scheduling issues of the RTI resources in the WAN.Though deploying various of the GRID-RTI into a cluster-RTI-federation,using heartbeat mechanism to guarantee the effectiveness of RTI services,designing a specialized scheduling method to ensure RTI services load capacity,the author develops the grid based union simulation platform.By the theoretical analysis and the actual test,it proves this platform can completely resolve the bottleneck of a single RTI issue and can realize the RTI resources sharing in the WAN.It provides a good support for the large-scale,multi-federal complex simulation system.更多还原
