stack-stitching
Restructure the call flow during Survey analysis to attach stacks to a point introducing a parallel workload.
GUI Equivalent

Syntax
--stack-stitching --no-stack-stitching |
Default
On (stack-stitching)
Actions Modified
collect=survey
Usage
The option restores a logical call tree for Intel® oneAPI Threading Building Blocks (oneTBB) or OpenMP* applications by catching notifications from the runtime and attaching stacks to a point introducing a parallel workload.
Disable when Survey analysis runtime overhead exceeds 1.1x
Disabling can decrease collection overhead and significantly decrease finalization overhead depending on workload.
Example
Run a Survey analysis. Disable stack stitching.
