One perameter to mark critical function is high CPI, But what are the other perameters to determine that? Specifically in the general exploration result from vtune, in the given formula (when i hovered on pink color CPI):
Threshold: (CPU_CLK_UNHALTED.THREAD / INST_RETIRED.ANY > 1) * (CPU_CLK_UNHALTED.THREAD / > 0.05)
What is this second part (in bold italic). How vtune marks pink color for some CPI values.
