Hello there, I've some questions and I would very much apreciate any help.
I'm profiling a toy benchmark using VTune Amplifier Lightweight hotspot analysis and analyzing the CPU utilization histogram on the Top-down Three tab. My question is: in the histogram If I zoom sufficiently I see that one of my threads has CPU Time = 0.0% this means what? That the CPU is waiting memory/cache ? In this same graph I see some bars with CPU Time above 7000%, how could that happen? How CPU Time is calculated?
Please see the image attached for a example.
