摘　　要：高速的RDMA网络设备已经被广泛部署在现代数据中心。RDMA可以从两方面加速分布式系统:首先可以提供一种快速的消息处理机制,其次RDMA提供了新的硬件原语。这极大地提升了处理器的利用率以及对RDMA的使用率,但是需要重新设计系统。介绍了RDMA的研究进展,概述了近年来利用RDMA加速分布式系统的工作,包括基于RDMA重新设计的系统以及如何更好地利用RDMA的设计,并给出了未来的研究方向。Fast network devices with RDMA support have been price-compatible with traditional network primitives such as Ethernet, and it＇s now widely deployed in modern data centers. RDMA can be used in two ways. Firstly, it can optimize the messaging primitive in distributed applications. The second way is to redesign the applications with RDMA＇s onesided features. One-sided features provide high CPU utilizations and high network performance, but the system should be redesigned. The research progress of RDMA was introduced. An overview on the research efforts on using RDMA for distributed systems was presented. The works on how to use RDMA to redesign systems and the works on how to better leverage RDMA were included. The future research directions were also put forward.
