Data Migration Dynamic Load Balance Technology of DSMC Parallel Simulation

Abstract

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.
