Research Of Parallel Communication Protocol Based On Intelligence NICs

With the increasing development of the CLUMPS, and the infinite demand for bandwidth brought forward by applications, parallel communication technology is more meaningful to clusters. To this day, a great deal of parallel communication schemes have been put forward, most of which aimed at improving communication bandwidth by striping scheme. Usually, the striping scheme is based on RMA communication protocol, which is fitted with long messages, not with medium messages. However, statistical analysis shows that medium messages happened at large in application programs communication. To resolve this problem, a new parallel communication protocol, which is called Parallel Communcation Protocol Based on Intelligence NICs, is brought up.Based on the former works done by others, this dissertation firstly discussed the essential issues of Parallel Communication and investigated the disadvantage of parallel communication protocols that existed. Then we proposed a parallel communication scheme based on Intelligence NICs, presented its designed and implementation in detail, including the extended implementation of it.The experimental results showed that this implementation has a famous bandwidth performance for medium messages, satisfying our design goal by and large. Finally, we concluded the thesis and the work done by this author, and gave some aspects of research work that we might do next.
