| 摘 要： | 针对SMP机群的双层并行体系结构,研制出一种双层并行技术--在计算节点间采用MPI消息传递模式并行,而在计算节点内部采用OpenMP编译器指令模式并行.通过算例测试证明,采用该技术的航空CFD程序,并结合贪婪负载平衡分配技术进行并行计算,其效率可达94%,计算结果与实验值吻合.

| Abstract: | Based on two-level parallel structures of SMP cluster,a two-level parallel technique is developed,which uses a Message Passing Interface MPI between the nodes and Compiler directives OpenMP inside the nodes.A greedy load balancing technique is employed during parallel computing.Testing results show the parallel computing efficient of CFD codes with the two-level parallel technique gets up to(94%,)and computing results are in good agreement with the experimental data. |

| Keywords: | SMP cluster two-level parallel structure two-level parallel technique load balancing technique |
