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.
In the Choose Target and Analysis Type window, switch to the Analysis Type tab.
VTune Amplifier launches the
tachyon_find_hotspots application that takes the
balls.dat as input and renders an image displaying the execution time before exiting. VTune Amplifier finalizes the collected results and opens 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. For more details, check the Command-line Interface Support section of the VTune Amplifier Help.
