集群高效通信机制分析*

集群是当今高性能计算领域的重要发展方向，随着高速互联网络硬件的发展，低效的通信方式成为制约集群整体性能的关键因素。高效的通信机制能够更好地利用互联网络硬件为高性能计算提供更高性能的通信支持，通信性能通常都远高于传统的IP协议。

Analysis on High Performance Communication Mechanisms of Cluster System

In the high performance computing area, cluster has been playing an increasingly important role. With the development of high-speed intereonnection network, the traditional communication method becomes the main obstacle to the perfor manceof cluster system. This paper discusses several high performance communication mechanisms, which efficiently support high performance computing. Their performances are far better than that of traditional IP protocol.
