Hi,

Thanks for posting in Intel Communities.

There seems to be a small error in the command that you are using to perform the analysis.

The correct format for specifying the knobs along with the remaining VTune command is:

-knob KnobName=KnobValue

The corrected command is :

vtune -collect hotspots -knob sampling-mode=hw -knob enable-stack-collection=true -knob stack-size=0 (program)

Please do note that the knob stack-size=0 is not required for the command since by default VTune is designed to use unlimited stack size.
