| 摘 要： | 在由多计算机集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，在GCA模型的基础上，提出了一个基于能力优化机制的分组通信模型OGCM（Optimizing Group Communication Model）。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。

| Abstract: | For resolving the conflict problem of the peak communication in data-intensive Grid that composed of computer clusters,an optimizing group communication model (OGCM) based GCA~([6]) was discussed.The experiment results show that this model effectively resolve the low efficiency during the peak communication in Grid.It can be fit for the data-intensive parallel computing based on Grid. |
