摘要
随着多核处理器的发展和计算需求的不断增长,高性能计算系统规模不断增大。使用模拟器对高性能计算系统进行模拟,对系统设计及优化有着重要的作用,互连网络模拟则是其中不可或缺的一部分。设计实现了一种基于OMNet++的大规模InfiniBand互连网络模拟系统,该系统通过记录的并行程序MPI消息来驱动网络仿真过程,可以模拟互连网络在程序运行过程中的工作状态,并可与消息驱动的高性能计算机模拟系统集成。通过与真实集群中节点间通信时延做对比,验证了模拟精度,并测试了模拟性能。
With the development of multi-core processors and the continuous growth of computation requirements,the scale of high-performance computer systems continues to increase.Using simulators to simulate high-performance computing systems plays an important role in system design and optimization,and the interconnection network simulation is an indispensable part of it.This paper designs and implements a large-scale Infiniband interconnection network simulation system based on OMNet++.The system drives the network simulation process through the recorded parallel program MPI messages.It can simulate the working state of the interconnection network during the program execution,and can be integrated with the message-driven high-performance computer simulators.By comparing with the communication delay between nodes in the real cluster,the simulation accuracy is verified and the simulation performance is tested.
