If you are not familiar with the Intel Advisor workflow, consider using the Advisor Workflow tab, which appears in the Intel Advisor GUI. This tab guides you through most steps of the Intel Advisor workflow, lets you run the Intel Advisor tools with your program, and keeps track of your progress through the workflow. After you run an Intel Advisor tool with your program, view the tools' output in the Result tab.

Note
Before you run an Intel Advisor tool, build a target executable of your program using the recommended Release or Debug build settings. For the Survey and Suitability tools, Intel recommends a Release build (debug information and moderate optimization). For the Dependencies tool, Intel recommends a Debug build (debug information and no optimization). Before building the target for the Suitability and Dependencies tools, add source annotations into your program to define at least one parallel site and task(s) within each site.
