Filtering Capabilities
Application Performance Snapshot can handle applications with thousands of
MPI ranks running in parallel. For such applications the aggregated result
charts may contain thousands of lines, which makes the results nearly
impossible to read.
The tool provides filtering capabilities to make the results tables
shorter.
There are two independent filters in the tool, which can be applied to any
table diagram:
- Filtering by key metric
- Filtering by number of lines
Note
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
