インテル® VTune™ Amplifier 2018 ヘルプ
VTune Amplifier displays [Skipped stack frame(s)] in the grid panes.
VTune Amplifier did not unwind the stack to reduce data collection overhead, and failed to resolve the stack heuristically.
You may collect deeper stacks by creating a custom event-based sampling analysis and increasing the Stack size option value in bytes (-stack-size option in CLI), though beware that this also increases the collection overhead.
