Intel® Advisor Help
The Total Time metrics shown on the right side of the source code show how the time is distributed in this function.
When investigating opportunities for adding parallel execution, look for a loop or a group of call sites that have significant Total Time.
To propose parallel code regions where you might use parallelism, add annotations
into your sources.
Intel Advisor Suitability and Dependencies tools use these annotations to predict the likely parallel characteristics of your program. Each parallel code region (site) executes one or more tasks, where each task's work can be divided up safely amongst multiple cores.
If you are not familiar with
Intel Advisor annotations, read the topic
2. Annotate Sources.
If you have found a good location, double-click a line to open the code editor with that file. When using the Intel Advisor GUI, the editor defined by the Options > Editor dialog box appears with the file open at the corresponding location.
You can use the annotation assistant pane to help you add parallel site and task annotations to your sources.
For a parallel code region, the Total Time (and Loop Time) shows the sum of the CPU time for all threads (see the topic Using Partially Parallel Programs with Intel Advisor Tools).
