目前，网络通信软件的处理开销已成为影响机群系统性能的瓶颈，为了提高机群系统的网络性能，本文设计了一种用于机群系统的快速消息传递机制FMP（FastMessagePassing），并在Myrinet网络上加以实现．在Ultra2上的测试表明，FMP单字节数据包单向通信延迟为11．2μs，8K数据包网络带宽达到338Mb／s，较好地发挥了Myrinet网络硬件的性能，达到了减少通信开销，提高网络带宽的目的．
At present, the processing overhead of network communication software has become a bottleneck affecting the performance of cluster system. In order to improve the network performance of cluster system, a fast message transfer mechanism FMP (Fast Messaging System) for cluster system is designed and applied on Myrinet network achieve. Tests on Ultra2 show that the unidirectional communication delay of FMP single-byte data packet is 11.2μs and the bandwidth of 8K data packet reaches 338Mb / s, which has played a good role in the performance of Myrinet network hardware, reducing the communication overhead and increasing The purpose of network bandwidth.
