Annotation Report, Reduction Row

This special-purpose annotation marks a line that computes a reduction in a loop. Marking the line as a reduction causes the Dependencies tool to ignore the data race.

To view the source code for this annotation, click the icon.

Reductions require special treatment when translating to parallel code (see the help topics Special-purpose Annotations and About Replacing Annotations ... for your parallel framework below).

When to View the Annotation Report

Use the Annotation Report window to view the types of annotations present in your project sources and access their locations. You can view the Annotation Report at any time to check the annotations. In addition:

  • Intel recommends that you view annotations during Adding Parallelism to Your Program workflow step to help you locate site, task, lock, and other annotations that should be replaced by parallel framework code.

  • When using the Intel Advisor product GUI, you can use this report to verify that the correct sources have been defined in the Project Properties > Source Search tab.
