Problem: Guessed Stack Frames

Cause

VTune Amplifier did not unwind the stack to reduce data collection overhead, but resolved the stack heuristically.

[Guessed stack frame] is considered to be a system function. If the Call Stack Mode filter bar option is set to User/system functions, the VTune Amplifier displays [Guessed stack frame(s)].

Solution

To avoid displaying [Guessed stack frame(s)], set the Call Stack Mode filter bar option to Only user functions.
