摘　　要：随着MPI-2的发布,单边通信越来越受到广泛的关注。集群系统中单边通信将是一个重要的发展方向,由IBM研制的BlueGene/L系统就是一个典型例子。在PowerPC架构上实现了一种基于RapidIO的单边通信接口,为下一步与MPICH2的连接实现迈出了重要一步。基于RapidIO的单边通信接口,将使整个网络达到低开销、高带宽和低延时,集群系统的性能也必将得到极大的提高。With the release of MP-2, increasing attentions are focused on monolateral communication. The monolateral communication will be a very important direction in Clustered System,the Blue Gene/L developed by IBM is just a typical example. This paper presented the implementation of a monolateral communication interface based on RapidIO on PowerPC architecture, which strides forward for achieving the next step of connecting with MPICH2. The RapidIO based monolateral communication will bring the whole networks with features of broad bandwidth, low cost and small latency, and the performance of the Clustered System will also be enhanced greatly.
