Abstract

We present an integrated approach to deal with timestamp consistency, and trace based performance analysis techniques for distributed parallel applications. Our trace generation facility captures message passing and system events such as process dispatch with minimal trace overhead. Trace driven analysis tools are developed for post execution analysis, reporting information such as the time stolen by other processes in each node, and the observed message passing time and local wait time for each message. We then present our techniques to reduce total elapsed times based on observed message passing times and local wait times.
分布式并行应用程序的基于跟踪的分析和调优
我们提出了一种集成的方法来处理时间戳一致性和基于跟踪的分布式并行应用程序的性能分析技术。我们的跟踪生成工具以最小的跟踪开销捕获消息传递和过程调度等系统事件。跟踪驱动的分析工具是为执行后分析而开发的,报告信息,例如每个节点中其他进程窃取的时间,以及观察到的消息传递时间和每个消息的本地等待时间。然后,我们介绍了基于观察到的消息传递时间和本地等待时间来减少总运行时间的技术。
