Intel® Advisor Help
Running your target application with the Intel® Advisor can take substantially longer than running your target application without the Intel Advisor. Depending on an accuracy level and analyses you choose for a perspective, different overhead is added to your application execution time. For example:
Runtime Overhead / Analysis |
Survey |
Characterization |
Dependencies |
MAP |
|---|---|---|---|---|
Target application runtime with Intel® Advisor compared to runtime without Intel® Advisor |
1.1x longer |
2 - 55x longer |
5 - 100x longer |
5 - 20x longer |
Use the following techniques to skip uninteresting modules and/or analyze only interesting modules.
Minimize collection and finalization overhead.
Applicable analyses: Survey, Characterization with Trip Counts and FLOP collection enabled.
Use to...
Exclude modules you cannot optimize, such as third-party code.
Include a small number of modules of interest.
Note: In the commands below, make sure to replace the myApplication with your application executable path and name before executing a command. If your application requires additional command line options, add them after the executable name.
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, where [Name] is Survey or Trip Counts and FLOP.
Use the advisor CLI action options --module-filter-mode=exclude and --module-filter=<string>. For example:
advisor --collect=survey --project-dir=./advi_results --module-filter-mode=exclude --module-filter=foo1.so,foo2.so -- ./myApplicationSet Project Properties > Analysis Target > [Name] Analysis > Modules > Include only the following module(s) and identify the modules.
Use the advisor CLI action options --module-filter-mode=include and --module-filter=<string>. For example:
advisor --collect=survey --project-dir=./advi_results --module-filter-mode=include --module-filter=foo1.so,foo2.so -- ./myApplication
