Analyze Code
You identified a hotspot function with a number of hardware issues. Double-click the
multiply1
function in the Bottom-up window to open the source code:
The table below explains some of the features available in the Source pane when viewing the event-based sampling analysis data.
When you drill-down from the grid to the source view, the VTune Amplifier automatically highlights the code line that has the highest event count. In the Source pane for the multiply1
function, you see that line 51 took the most of the Clockticks event samples during execution. This code section multiplies matrices in the loop but ineffectively accesses the memory. Focus on this section and try to reduce the memory issues.
