Detection of communication delay in unbalanced multithreaded networks under NUMA architecture

针对不平衡动态多线程网络通信延迟检测不精准的问题,提出了NUMA架构下不平衡多线程网络通信延迟检测方法。引入通信进程性能降低比例,分析NUMA架构下的不平衡多线程网络通信延迟结构。计算不平衡多线程的网络通信延迟数据并行处理时间,确定静态、动态延迟路径。分析NUMA架构延迟节点组织形式,计算从发生时间到发送时间产生的延迟,并根据静态、动态信息帧检测相应延迟。由实验结果可知,所研究方法静态通信情况下的延迟时间最长为1.45 min,最短为0.5 min,与实际延迟时间一致;动态通信情况下的延迟时间最长为9 min,最短为3.1 min,与实际延迟时间仅存在最大为0.3 min的误差。

Aiming at the problem of imprecise delay detection in unbalanced dynamic multi-threaded network communication,a communication delay detection method for imbalanced multithreaded networks under the NUMA architecture is proposed.Introduce the proportion of communication process performance reduction and analyze the unbalanced multi threaded network communication delay structure under the NUMA architecture.Calculate the parallel processing time of network communication delay data for unbalanced multithreading,and determine static and dynamic delay paths.Analyze the organizational form of delay nodes in the NUMA architecture,calculate the delay generated from the occurrence time to the transmission time,and the corresponding delay is detected according to static and dynamic information frames.According to the experimental results,the maximum delay time of the studied method in static communication is 1.45 min,and the minimum delay time is 0.5 min,which is consistent with the actual delay time.The maximum delay time in dynamic communication is 9 min and the minimum is 3.1 min,with a maximum error of 0.3 min compared to the actual delay time.
