Abstract

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.
