集群局域网内高性能通信协议的研究

集群已经成为了主流的并行计算平台,但集群计算系统的性能受限于互连通信的开销、延时和带宽。随着技术的不断改进,通信瓶颈从原来通信路径上的带宽转移到通信处理的软件开销。为了充分发挥硬件通信性能,作者提出、研究、设计和实现了局域网内高性能通信协议。该协议的突出特点是充分利用了集群局域网的高速高可靠特点,简化协议处理开销,达到通信的高效性;提出了数据合并的思想,能将大量的小消息合并成大消息传输,能充分提高传输性能。经测试,该协议的性能比传统TCP/IP协议有较大改进。

The Study of High Performance Communication Protocol in Cluster Local Networking

Cluster computer system has become the mainframe parallel computing environment ,but its performance is limited to the overhead,delay and bandwidth of interconnect.With the technology advancement ,the communication bottle-neck is moved from network hardware to the handle of communication protocol.In order to improve the data deliver performance of cluster system,this paper provides and designs a SLNP(Simple Local Networking Protocol).The outstand-ing characteristic of SLNP is:making full use of the high bandwidth and high reliability,it simplifies the protocol han-dling and improves the communication efficiency;providing the idea of data combination,it can combine the little mes-sage into a large one,and this can improve the efficiency of network delivering.We have implemented part of protocol.The measurement shows that SLNP works better than traditional protocol such as TCP/IP and UDP/IP.
