Manual for bottleneck_report.py script
Script name and location
| name | bottleneck_report.py | | location | VKGLCTS_ROOT/scripts/log |
Description
The script parses qpa report file and produces an output containing three lists:
-
A list of single tests sorted descending by the duration of execution. On this list one can find exceptionally lenghty tests.
-
A list of groups of tests sorted descending by their total duration of execution. This list can be used to spot a groups that either contain a large amount of tests or multiple slow tests.
-
A list of groups of tests sorted descending by an average duration of the test in this group (a total duration of group divided by number of tests in the group). Presents groups containing slow tests.
This script requires that qpa file contains tests timing data (one created with sufficiently new version of cts framework).
Usage
python path/to/bottleneck_report.py TESTLOG COUNT
TESTLOG - a fully qualified path to read-accessible qpa report file.
COUNT - number of entries output in each section.
Example
python bottleneck_report.py c:\khronos\build\external\vulkancts\modules\vulkan\TestResults.qpa 5
Produces following output:
