An efficient communication protocol for PC clusters

When clusters are used in parallel computing, the communication speed between processes is the bottleneck due to low network communication bandwidth. In this paper, we overview some methods used to improve communication performance, and introduce a new transport protocol that we have designed and implemented based on Ethernet. In addition, the TCP/IP protocol is replaced by the new protocol in cluster computing. This work will used in CSCW applications. The results show that parallel computing using the new protocol on an Ethernet compared to using the TCP/IP protocol on an Ethernet can provide larger communication bandwidth and improve the performance of a cluster system.
