Insert Annotations Using the Annotation Wizard

Adding annotations requires you to reference the annotation definitions include file as well as include it from each source file that contains Intel® Advisor annotations.

The Annotation Wizard is supported only in the Microsoft Visual Studio* code editor. Alternatively, you can copy annotation code snippets using any editor.

In Visual Studio* 2022, Intel Advisor provides lightweight integration. You can configure and compile your application and open the standalone Intel Advisor interface from the Visual Studio for further analysis. All your settings will be inherited by the standalone Intel Advisor project.
In most cases, you do not need source annotations when using Intel® Advisor, except for the Suitability analysis of the Threading perspective. When analyzing your application with other perspectives, such as Vectorization and Code Insights or Offload Modeling, you can analyze all parts of your code automatically or use Intel Advisormark-up capabilities, which do not require you to recompile your application.

Use the annotation wizard to add Intel® Advisor annotations to your program.

  1. In the Visual Studio* editor, select the code section that you wish to annotate.
  2. Right-click to open the context menu and select Intel Advisor [version]> Annotation Wizard...
    The Annotation Wizard opens with the default Annotate Site – select task annotations below annotation selected:

  3. From the Choose the Annotation Type drop-down, choose the appropriate annotation type. For example, if you want to add the parallel site (parallel code region) annotations and a single task annotation within that site, start by selecting the site code block and choose Site and Iteration Task Snippet, single iteration task in loop. In other cases, you may need to add two separate annotations - one for the site and one for the task(s). In this case, after adding them, move individual annotation lines around your existing site and task(s) code.
    Your code appears in the Example section of the dialog, with the annotation line(s) highlighted in red font.
  4. Click Next to configure the parameters of the opening annotation line.
    For Annotation types that include parameters, page 2 of the wizard appears. Site, task, and other annotations take name arguments. You should replace the added name with a name that helps you quickly identify its source location. For example, if MySite1 is the argument to a site annotation, replace it with a meaningful function or loop name. The added name must be unique amongst the annotations in this project. For Annotation types that do not include parameters, go to step 8.
  5. Specify the parameter values for the first parameter in the Annotation type, or use the default text that appears in the wizard.
    The highlighted annotation line now has your specified parameter value entered in the annotation line.
  6. Click Next to configure, or keep the default text for the next parameter. Repeat for all the parameters.
    The highlighted annotation line now has all parameters filled in with values entered in the annotation line.
  7. Click Next to go to page 3 of the wizard and review the annotation line(s) before adding it to you code.
  8. Click Finish to add the annotation line with your specified parameters to your code.
    The Wizard closes and the editor shows the annotation lines added to the code.

The annotation line(s) are added in the code editor.

If a loop only executes a single statement and does not contain an opening brace ({) to allow multi-statement execution, add braces ({ and }) around the existing statement and the annotation.
