Explore options to run, stop, cancel, or pause your performance analysis with Intel® VTune™ Amplifier.

Run Analysis from Standalone Interface

To run an analysis:

  1. Create/open a VTune Amplifier project.

    From the Configure Analysis window:

    • Specify an analysis system from the WHERE pane.

    • Specify an analysis target from the WHAT pane.

    • Select an analysis type from the HOW pane.

  2. At the bottom of the Configure Analysis window, click the Start button to run the analysis.

    To pause the analysis at the application start and then manually resume it when required, click theStart Paused button.

Note

The Start button may be disabled if you either did not specify the analysis target or selected the analysis type that is not supported by your processor.

Run Analysis from the Microsoft Visual Studio* IDE

  1. Open your target in Visual Studio.

  2. Build your target in the Release mode in the development environment of your choice.

  3. Click the Configure Analysis button on the VTune Amplifier toolbar to choose and configure an analysis type in the Configure Analysis window.

  4. At the bottom of the Configure Analysis window, click the Start button to run the analysis.

    To pause the analysis at the application start and then manually resume it when required, click the Start Paused button.

Stop/Cancel the Analysis

When you run the analysis, the command toolbar at the bottom of the Configure Analysis window is updated with a set of buttons for managing the data collection.

  • To stop the analysis, click the Stop button or press Ctrl-C.

    VTune Amplifier stops collecting data and opens the analysis result.

  • To cancel the analysis, click the Cancel button.

    VTune Amplifier stops collecting data and displays the warning message: Collection was cancelled by the user. The data cannot be displayed.

Open Analysis Results

VTune Amplifier analyzes the target, finalizes the result, and opens the collected data in the default viewpoint. The data collection results (*.amplxe file) show up in the Solution Explorer (for the VTune Amplifier integrated into Visual Studio)/Project Navigator (standalone) under the project folder, in the alphabetical order. For executable files imported to the Visual Studio project, the data result node appears at the solution level. Double-click a result to open the collected data in the default viewpoint.

Note

  • You can provide a meaningful name for the result (for example, application name) for better identification. To do this, select the result, right-click and choose Rename. The file extension *.amplxe cannot be changed.

  • To change the result name template or the default directory for result location, go to Tools > Options (or Options... in the standalone interface menu) and select Intel VTune Amplifier version > Result Location from the left pane of the Options dialog box.

  • You may program hot keys to start/stop a particular analysis. For more details, see http://software.intel.com/en-us/articles/using-hot-keys-in-vtune-amplifier-xe/.
