摘　　要：在由多计算机机群构成的数据密集型网格环境下,为了解决通信峰值阶段的通信冲突问题,提出了一个基于能力优化机制的通信模型;给出了由多机群组成的数据密集型网格数据节点(DGDN)等形式化定义。利用计算节点通信能力、机群网络通信能力、主被动队列和分组优化策略、反向流压控制机制,研究了单个机群内的通信模型,并描述了网格上的通信模型。理论分析和实践表明,该模型有效地解决了数据密集型网格环境下通信峰值所造成的并行计算效率低下的问题。该模型适合于基于网格的数据密集型并行计算。For resolving the conflict problem of the peak communication in Data-intensive Grid that is composed of Computer Clusters,a optimizing communication model （OGCM） is discussed.A series of formal definitions,such as the Data-intensive Grid Data Node （DGDN）,are given.Using the ability of the computer communication and the network of cluster,the mechanism of the active and passive queue,the optimizing group strategy and the anti-stream control techniques,a communication model in single Computer Cluster is studied.Based on OGCM,the communication model is described in DGDN.The analysis and experiment results show that this model effectively resolve the low efficiency during the peak communication in Grid.lt can be fit for the data-intensive parallel computing based on Grid.
