Reduced communication protocol for clusters

With the development of CPUs and communication networks, workstation clusters using message-passing mechanism become a crucial role in the field of network computing. Today´s clusters are mainly connected by networks running traditional communication protocols (such as TCP/IP). The high overheads of these protocols make many parallel applications running on clusters inefficient using the potential computation power provided by the workstations and the networks. A method to solve this problem is to construct reduced communication protocol. This paper gives a detailed analysis of overheads produced by traditional protocols and provides some global strategies to design a reduced communication protocol. Our implementation method of such a protocol is described here together with some core algorithms and the testing results
