Intel® Advisor Help
Running your target application on all binary modules with the Intel Advisor can take substantially longer than running your target application without the Intel Advisor. For example:
Runtime Overhead / Analysis |
Survey |
Trip Counts & FLOP |
Roofline |
Dependencies |
MAP |
---|---|---|---|---|---|
Target application runtime with Intel Advisor compared to runtime without Intel Advisor |
1.1x longer |
3 - 8x longer |
3.1 - 8.1x longer |
5 - 100x longer |
5 - 20x longer |
Use the following techniques to skip uninteresting modules and/or analyze only interesting modules.

---|---|---|
|
GUI control: Project Properties > Analysis Target > [Name] Analysis > Modules options and field CLI: action option: -module-filter-mode=include | exclude and -module-filter=<string> |
Minimize collection and finalization overhead.
Applicable analyses: Survey, Trip Counts and FLOP.
Use to...
Exclude modules you cannot optimize, such as third-party code.
Include a small number of modules of interest.
To implement, do one of the following before/while running the desired analysis:
Set Project Properties > Analysis Target > [Name] Analysis > Modules > Exclude the following module(s) and identify the modules.
Use the CLI action options -module-filter-mode=exclude and -module-filter=<string>. For example:
advixe-cl -collect survey -project-dir ./myAdvisorProj -module-filter-mode=exclude -module-filter=foo1.so,foo2.so -- ./bin/myTargetApplication
Set Project Properties > Analysis Target > [Name] Analysis > Modules > Include only the following module(s) and identify the modules.
Use the CLI action options -module-filter-mode=include and -module-filter=<string>. For example:
advixe-cl -collect survey -project-dir ./myAdvisorProj -module-filter-mode=include -module-filter=foo1.so,foo2.so -- ./bin/myTargetApplication
