The message passing system is crucial to the computational performance of workstation clusters. With the fast growth in performance of networking device, the unnecessary overhead in traditional TCP/IP protocol has become the bottleneck of communication speed. To fully exploit the communication potential of the fast hardware, this paper introduces FMP, a new communication protocol specifically designed for Myrinet. FMP, which consists of a network part, is a concise protocol. The physical layer is assumed to be error free and thus the protocol becomes extremely simple and highly efficient. Compared with TCP/IP, the performance of FMP is much better. In this article the essential techniques used in the protocol are discussed and some results are presented.
