Loop Trip Count

Enable the stack collection for the hardware event-based sampling analysis and configure the Intel® VTune™ Amplifier to statistically approximate the number of trip counts for sampled loops.

Sample After Value

For a custom event-based sampling data collection, set up the Sample After Value (SAV) that is a frequency with which the Intel® VTune™ Amplifier interrupts the processor to collect a sample during hardware event-based data collection. SAV is measured as the number of events it takes to trigger a sample collection.


Configure the Intel® VTune™ Amplifier to focus your performance analysis on a task - program functionality performed by a particular code section.
