Data Migration Dynamic Load Balance Technology of DSMC Parallel Simulation
【摘要】 针对DSMC并行仿真中的负载变化特点,提出了DSMC并行仿真数据迁移的动态负载平衡技术。测试结果证明该技术能有效提高DSMC并行仿真的计算效率。
【Abstract】 This paper analyses the load character of the DSMC parallel simulation caused by the free movement of molecules. A dynamic load balancing method based on data migration is presented. Moreover, a heavy-load-first algorithm in the location strategy and a load information adaptive cycle acquisition method are brought forward. The test result proves that the method and algorithm can reach a good load balance result.
