Hi,

I am experiencing a difference between the basic and advanced hotspots results, adn I cannot explain that.
I would expect similar results. The same code, same data were used for both.
Please, see attached picture.
Thanks for your help,

Peter

Hello Peter,

Did you collect advanced hotspots with stacks?

If no - could you please do this and compare? The point is that VTune might not classify spins/overheads w/o stacks in the full way so the metrics based on this differ.

Thank you, Regards, Dmitry
