Filtering Capabilities
Application Performance Snapshot can handle applications with thousands of MPI ranks running in parallel. Consequently, the aggregated result charts for these large applications may contain thousands of lines To create smaller tables of results, you can filter the results in a few ways:
- By key metric
- By rank
- By node
- By function
Filters do not skip one line because it is substituted with the message about the skipped lines, which also takes one line.
Filters are enabled by default, and the tool behavior is the same as with the key combination:
–V 1 –T 1 –N 5
To disable the filters entirely, use the -F key, or the following key combination:
–V 0 –T 0 –N 0
