Before running an analysis, choose a configuration level to influence Intel® VTune™ Amplifier analysis scope and running time. In this tutorial, you run the Basic Hotspots analysis to identify the hotspots that took much time to execute.
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.
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.
