摘　　要：采用LAM-MPI实现节点间粗粒度并行和OpenMP实现节点内细粒度并行这种混合编程方式为SMP机群提供了一种有效并行策略.讨论了LAM-MPI+OpenMP混合编程环境的快速搭建以及多粒度混合并行编程方法,实现了分子动力学模拟问题的多粒度混合并行算法,并在搭建的8节点SMP机群环境中完成测试工作.Adopting LAM- MPI to implementate coarse grain method in nodes and OpenMP to implementate fine grain method in one node mode provides an effective strategy for SMP Cluster. The paper analyses the advantage and disadvantage of MPI and OpenMP, discusses the fast building of MPI and OpenMP hybrid programming environment and algorithm of multi-grain hybrid parallel. Implement a multi - grain hybrid parallel algorithm on MD problem, and test it on SMP Cluster which has 8 nodes.
