How a transparent and extendable automatic rollback mechanism design using State Exchange Object and Incremental State Saving technique was implemented in KD-PARSE,and a parallel discrete event simulation engine and supporting environment,to facilitate its optimistic synchronization algorithms used in parallel discrete event simulation.
介绍了并行仿真驱动及支持软件KD-PARSE基于状态交换对象(SXO),采用增量式状态保存法,实现透明、可扩展自动回退机制以支持并行离散事件仿真中的乐观时间管理算法的方法,并给出了该回退框架的整体结构设计。
The similarities and differences of parallel and distributed simulation, the synchronization and rollback mechanisms were described first, then μsik was analyzed from 4 aspects: architecture,.
该文首先阐明并行仿真与分布仿真的异同,以及并行仿真中的同步与回退机制,接下来对μsik从体系结构、数据结构、调度过程和事件发送过程等方面进行分析,然后在μsik中增加了两种事件发送机制:保守发送机制和限制的乐观发送机制,对改进的内核进行测试并对测试结果做了详细分析,结果表明增加的事件发送机制能够提高系统性能。
