计算机仿真中并行处理技术的研究

用多机系统进行并行仿真是解决大规模连续系统实时仿真问题的有效途径。多机并行仿真中关键要解决的问题，是如何有效地将一个仿真任务分配到多机系统上并发执行，并获得高的加速比。本文介绍了作者自行研制的并行仿真软件支撑环境ＰＡＲＳＩＭ，它可将一个传统单机上串行执行的仿真程序自动转换成在同构型多机系统上高效并发执行的并行仿真程序，并就并行性识别，多任务自动划分等问题展开了讨论，给出了相应的算法和应用实例。

STUDY OF THE PARALLEL PROCESSING TECHNIQUES FOR COMPUTER SIMULATION

The key problem in parallel simulation is how to allocate a task to a multiprocessor system to execute concurrently with high speedup.A supporting software environment for parallel simulation(PARSIM) designed by the authors is introduced in this paper,by which the sequential simulation programs executed on uniprocessor systems can be automatically transformed into the parallel programs to be effectively executed on multiprocessor systems.The problems of parallelism exploiting,task auto-partitioning,load balancing and interprocessor communication overhead reducing are discussed,some algorithms and application examples are given.
