MPI Debugging Tips and Tricks

SESSION: MPI Debugging Tips and Tricks

EVENT TYPE: Birds of a Feather

TIME: 12:15PM - 1:15PM

SESSION LEADER(S):Chris Gottbrath


If you've ever had to troubleshoot an MPI job that was crashing, hanging or producing invalid results you know that it can be both daunting and fascinating. This BOF is an open forum for HPC developers to share war-stories from the debugging battlefront and strategies that they use to simplify understanding and eliminating defects in parallel applications. We're looking for brief presentations that recount specific experiences, outline useful strategies, and give information on clever and helpful ways of using or customizing available tools. Some specific topics might include: working with problems at scale, dealing with problems that come and go randomly, dealing with memory errors, strategies for comparative debugging, ways to customize the display of data, automatic/script based debugging, reverse debugging, or dealing with accelerators. A handful of short user talks of 5-15 minutes each will be followed by a general discussion. While this session is organized by Rogue Wave this session features HPC users and is anticipated to cover a range of tools and techniques for parallel debugging. Community members interested in reserving time in this session should contact
