Parallel Framework for HLA Federate Oriented to Simulation Component on Multicore Platform

Abstract

提出了一种面向仿真组件的并行联邦成员框架,以解决基于HLA(high level architecture)复杂仿真系统联邦成员开发的问题,并提升多核处理器环境下联邦成员的运行性能.并行联邦成员框架通过仿真组件的组合、装配来构建联邦成员.通过仿真引擎管理、数据分发管理、对象管理、组件管理服务和负载平衡功能,并行联邦成员框架为仿真模型构建了一个多核的并行执行环境,并确保并行成员能与RTI 正确交互.通过实验来研究并行成员框架引入的额外开销,并比较并行成员和普通成员的性能.实验结果表明,并行框架能够充分利用多核处理器的计算能力来减少仿真系统运行时间,提高系统性能.;A simulation component, oriented as a parallel framework for federate, was raised to facilitate federate development and improve execution performance of federate on multicore platform. Simulation components were employed to compose and assemble federates in parallel framework. With simulation engine management service, data distribution management service, object management service, component management service and load balancing of parallel framework, a multicore parallel environment was provided for simulation component, which also assured correct interactions between parallel federates and RTI. Experiments were carried out on the extra overhead introduced by parallel framework and performance comparisons between normal federate and parallel federate were made. Results showed that parallel framework fully exploited multicore processors with reduced execution time and improved performance of simulation system.
