| Abstract: | Based on multi-level storage architecture of popular computer and message passing parallel programming mode, this paper discussed that the parallel program of lattice Boltzmann is optimized in cache. The results show that the Cache missing rate can be reduced by 80%, performance can be increased by 20% and preprocessing method can also improve parallel performance. |
