Summary ViewSummary ViewThe Summary view opens by default if you collected sampling data using the Clockticks event only.
You can open the Summary view for any sampling Activity that includes the Clockticks event from the Activity result pop-up menu. To do that, select the Activity result from the Tuning Browser, right-click and select Open Summary View... from the pop-up menu.
During data collection, the VTune(TM) Performance Analyzer collects samples of active instruction addresses after the specified number of occurrences of the event(s) and writes them to a file. The Summary view displays the general information on the most active functions based on the focus mode selected in the Sampling: Summary View Preference Options:
Hotspot Summary by Process: If you specify one process as a module of interest, the Summary view shows the most active functions in your application.
Hotspot Summary by User Processes: If you specify several processes as modules of interest, the Summary view shows the most active functions in your processes.
Hotspot Summary by User Modules: If you specify some modules as modules of interest, the Summary view shows the most active functions in your modules.
Hotspot Summary by Whole System: if you don't specify any modules of interest, the Summary view shows the most active functions on your system.
