Problem: Guessed Stack Frames

VTune
Profiler
displays
[Guessed stack frame(s)]
in the grid panes.

Cause

VTune
Profiler
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
Profiler
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
.
