Research on Distributed Database High-Performance Computing Method Based on InfiniBand

Abstract

With high bandwidth and low latency, the InfiniBand protocol has been widely used in distributed databases and high-performance computing in recent years. Compared to traditional PCI bus, 10 Gigabit Ethernet and Myrinet technology, InfiniBand in addition to the delay and bandwidth on the dominant and has a better quality of service. This paper first introduces the basic situation and principle of InfiniBand protocol and its application status in high performance computing field. Based on InfiniBand protocol, this paper proposes a high-performance message passing method based on remote direct memory access, such as delay and peak bandwidth Indicators have very good characteristics. The experimental results show that compared with the traditional technology, the improved method proposed in this paper reduces the delay of more than 20% and the bandwidth is more than doubled, and improves the system performance by reducing the transmission time of the control message.
