Error Message: No Annotations Found

Symptoms

  • A message appears when you click the
    Annotation Report
     button and you have not yet added
    Intel® Advisor
     annotations to your program, or you have not yet run the Suitability and Dependencies tools after adding the annotations.
  • When using the
    Intel® Advisor
     GUI while viewing the
    Summary
     window, you see a message
    No annotations detected in your project sources
     when your sources do contain annotations.

Cause

The Suitability and Dependencies tools use the annotations you added to your program to analyze your running program and populate the
Annotation Report
 window with data. However, before you run these tools to collect data about your running program, you need to add annotations and perform related actions.
When using the
Intel® Advisor
 GUI, make sure that the appropriate project properties have been specified so the
Intel® Advisor
 tools can find the correct source location(s).
Also, if your sources contain huge source files that contain annotations, be aware that only the first 8 MB of each file will be parsed for annotations (for performance reasons). This could possibly cause mismatched or no annotations found messages.

Possible Solution

  • Do the following:
    1. Use the Survey analysis to find where your program spends its time. Choose at least one possible parallel code region (site) and identify code that might execute independently as a task.
    2. Use the code editor to add at least one pair of parallel site annotations that contain task annotation(s) into your program. You can copy annotation code using the bottom of the
      Survey Report
       or
      Survey Source
       windows.
    3. Make sure that these annotations are executed by the selected project or the selected startup project (Windows* OS).
    4. Make sure that you reference the annotations definitions file in the source modules where you added the annotations.
    5. Reference the annotations definition directory and provide other build settings.
    6. If you are using the
      Intel® Advisor
       GUI, check the
      Project Properties
       dialog to make sure that source locations are specified in the
      Source Search
       tab.
    7. If your sources include huge source files that contain annotations (more than 8 MB per file), consider breaking each huge source file into several source files.
  • Windows OS only
    : If you selected the wrong startup project, select and build the correct startup project, run either the Suitability or Dependencies tool, and click the
    Annotation Report
     button.
