Detailed MPI Analysis

If the quick performance overview for your MPI application is not sufficient, you can use the advanced capabilities of Application Performance Snapshot to get a better understanding of the application flow.

You can break down the analysis results by MPI ranks, functions used, message sizes, and other entities, and filter the results for better readability. There is also support for MPI_Pcontrol operation, which allows you to analyze specific code blocks.
