For multi-core SMP cluster systems,this paper discusses hybrid parallel programming techniques based on MPI and OpenMP.We propose a new hybrid parallel programming methods that are aware of architecture hierarchy on SMP cluster systems.We design a hierarchically parallel algorithm on the N-body problem,and compared its performance with traditional hybrid parallel algorithms on the Dawning 5000A cluster.The results indicate that our hierarchically hybrid parallel algorithm has better scalability and speedup than others.
