摘要
针对异构集群并行效率不高的特点,通过分析由于计算系统设计不合理而产生的种种问题,提出了一种基于异构环境下的树型计算系统,用以兼容各类计算平台,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,并且通过实验验证了该系统的可行性。
In accordance with the feature of heterogeneous cluster parallel efficiency, a design of computing system based on tree structure under heterogeneous environment is proposed in this paper, by studying cause problems due to the unreasonable com- puting model design. The system is designed in order to compatible with all kinds of cmputing platform and 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.
