摘要
针对MPI集群通信的特点,通过分析当前网络的通信结构和MPI的点到点通信模式,提出了一种基于数据链路层的集群通信机制,用以减少协议开销和内存拷贝次数,从而提高集群节点间的通信性能,并且通过实验验证了该机制的可行性。
In accordance with the feature of MPI cluster communication, a mechanism of MPI communicaton based on Data_Link_Layer is proposed in this paper in order to induce protocol cost and times of memory copy, by studying the communication structure in current network and MPI point-to-point communication models. This mechanism improves cluster inter-node communication efficiency. Finally, we demonstrate the effectiveness of this mechanism through experiments.
