Based on the framework of BSP,a Hierarchical Bulk Synchronous Parallel(HBSP)performance model is introduced in this paper to capture the performance optimization problem for various stages in parallel program development and to accurately predict the performance of a parallel program by considering factors causing variance at local computation and global communication.The related methodology has been applied to several real applications and the results show that HBSP is a suitable model for optimizing parallel programs.
