摘　　要：介绍了软件 DSM系统 JIAJIA在 SCI网络上的实现 .利用 SCI的编程接口 SISCI重新设计和实现了 JIAJIA的通信模块 .并进一步对其进行了性能测试和分析 ,结果显示 ,在 SCI网络上 JIAJIA的性能得到了大幅度的提高 ;值得注意的是 。This paper introduces SVM system(also known as Software Distributed Shared Memory, Software DSM) briefly, and analyzes its behavior of communication in-depth. With SCIs API SISCI,this paper redesigns JIAJIAs communication module, tests and analyzes the systems performance. Compared with time spending on network communication, Overhead of SVM on small message is much larger than that on large message. And compared with Ethernet, the improved performance of large message is apparently more than that of small message in SCI net.
