Run Basic Hotspots Analysis

In this tutorial, you run the Basic Hotspots analysis to identify the hotspots that took much time to execute.

To run an analysis:

  1. From the VTune Amplifier toolbar, click the New Analysis button.

    The New Amplifier Result tab opens with the Analysis Type window active.

  2. On the left pane of the Analysis Type window, locate the analysis tree and select Algorithm Analysis > Basic Hotspots.

    The right pane is updated with the predefined settings for the Basic Hotspots analysis.

  3. From the right pane, select the Analyze OpenMP regions checkbox.

  4. Click the Start button on the right command bar.

VTune Amplifier launches the nqueens_parallel application that makes calculations, displays the execution time, and exits. VTune Amplifier finalizes the collected results and opens the analysis results in the Hotspots by CPU Usage viewpoint.

To make sure the performance of the application is repeatable, go through the entire tuning process on the same system with a minimal amount of other software executing.


This tutorial explains how to run an analysis from the VTune Amplifier graphical user interface (GUI). You can also use the VTune Amplifier command-line interface (amplxe-cl command) to run an analysis. If you run the example program from the VTune Amplifier command-line interface, specify 15 as a command argument. For more details, check the Command-line Interface Support section of the VTune Amplifier Help.
