提高工作站机群系统通信性能方法的研究

HOW TO IMPROVE COMMUNICATION PERFORMANCE FOR NETWORK OF WORKSTATIONS

工作站机群系统是目前并行处理技术的研究热点之一，而如何提高其网络通信的性能又是发展机群系统的关键。本文在分析影响网络系统性能因素的基础上，从软、硬件两方面着重讨论了高速网络技术。

Network of Workstations is becoming one of the leading technique in parallel processing, however, its poor communication performance seriously affects the speedup and efficiency of parallel computation. In this paper, we analyze four elements which dominate the cost of message-passing, then discuss several methods to minimize the communication overhead, such as high speed network technology, reduced communication protocol and Active Message. At last, we present two systems to show that these methods can make the networks more efficient.
