Analysis Charts
Apart from the summary page, which is displayed by default when the analysis is complete, Application Performance Snapshot provides capabilities for a more thorough MPI analysis. There are a number of charts that provide information about a certain aspect of the MPI application run.
Each chart has an associated command-line key of the aps-report tool. To view the desired chart, run aps-report with the corresponding key, for example:
$ aps --report ./aps_result_<postfix> -f # prints the function summary
Most of the charts support filtering, which can be enabled by using specific options. See Filtering Capabilities for details. For the list of all available command-line keys and options, use the --help option.
