Problem: Skipped Stack Frames

Intel® VTune™
Profiler
displays
[Skipped stack frame(s)]
in the grid panes.

Cause

VTune
Profiler
did not unwind the stack to reduce data collection overhead, and failed to resolve the stack heuristically.

Solution

You may collect deeper stacks by creating a custom event-based sampling analysis and increasing the
Stack size
option value in bytes ( option in CLI), though beware that this also increases the collection overhead.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
