Hardware Events Report

Intel® VTune™ Amplifier counts the number of hardware events during the Hardware Event-based Sampling Collection to help you understand how the application utilizes available hardware resources. Use the hw-events report type to display hardware events count per application functions in the descending order by default.

Example

This example generates the hw-events report for the specified Hotspots analysis (hardware event-based sampling mode).

$ amplxe-cl -report hw-events -r r001hs
