Run the Concurrency analysis to understand how effectively your application is parallelized.
To run an analysis:
- Select the Analyze Intel runtimes and user synchronization checkbox.
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. For more details, check the Command-line Interface Support section of the VTune Amplifier Help.
