摘要
聚合集群计算节点机的多接口用于多路径并发传输,引入多路传输控制协议(MPTCP)以提升开放消息传递接口(OpenMPI)的通信吞吐能力和并行计算性能,给出实验原型的组织结构及软硬件配置,重点分析传输路径宽带对称性与吞吐量的变化关系,以及不同传输控制协议栈的LIN-PACK基准测试的加速性能和单链路故障的自愈性能。结果表明,MPTCP双路并发的吞吐量较传统TCP提高89%,并行计算的最大加速比可达2. 63,并具备较好的故障自愈性能。
A design of multi-port aggregation and multi-path concurrent transmission is presented for anode computer of cluster computing. The multi-path transmission control protocol(MPTCP) is introducedinto an open message passing interface(OpenMPI) to upgrade communications throughput and parallelcomputing performance. The topology and the configuration of software and hardware of an experimentalprototype are given. The dependent relation of throughput on symmetry of transmission bandwidth,thespeedup of parallel computing by LINPACK benchmark over different transport stacks,and auto-recoveryagainst single link failure are analyzed. The results show that compared with the conventional TCP,thethroughput of MPTCP on dual-path is increased by 89%,the maximum speedup for parallel computing is2. 63-fold,showing better recovery in the presence of communications outage.
