| 摘 要： | 针对单层型MPI集群通信效率不高的特点,通过对比分析单层型结构和树型结构在集群聚合通信中的不同,提出了一种基于树型结构的MPI集群系统设计方案.用以降低全局通信流量和均衡主控节点负载,从而改善集群通信效率,使集群的扩展更加灵活,通过实验验证了该方案的可行性. |

| Abstract: | In accordance with the feature of flat-structure MPI cluster communication,a design of MPI parallel computing system based on tree structure is proposed in this paper by studying the difference of converged communications between flat-structure and tree-structure in order to induce global traffic and balance master node load.This design improves the efficiency of cluster communication and makes the cluster expansion more flexible.Finally,we demonstrate the effectiveness of this design through experiments. |
