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.

 

Refer: https://www.intel.com/content/www/us/en/develop/documentation/vtune-help/top/command-line-interface/command-line-interface-reference/stack-size.html

 

If this resolves your issue, make sure to accept this as a solution.

This would help others with similar issue. Thank you!

 

Thanks and Regards,

Diya
