| 摘 要： | Infiniband体系架构(IBA)是一种新兴的互联技术,它主要用于处理节点和输入输出节点之间的互联,从而形成一个系统级的网络.为了改进通信子系统的性能,IBA提供了很多特性,其中之一就是远程直接内存访问(Romote Direct Memory Access,RDMA).但是在标准的IBA实现中,对于控制报文和小报文使用发送接收操作来进行.本文提出了一种改进的RDMA实现,使得RDMA能够应用于控制报文和小报文,从而使得传输小报文和控制报文的延迟平均降低24%.

| Abstract: | Infiniband Architecture or IBA is a latest interconnection technology for interconnecting processing nodes and I/O nodes to form a system area network. To improve the performance of communication subsystem, IBA provides many characteristics, among which there is RDMA feature. Small messages and control messages are transmitted by using send/receive method in standard IBA implementation. The implementation of an improved RDMA is presented so that small messages and control messages can be transmitted in RDMA channel,and as a result ,the average latency of small messages and control messages transmission can be reduced by 24%. |
