Syntax

--stack-stitching

Default
On (stack-stitching)
Actions Modified
collect

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. 
advisor --collect=survey --no-stack-stitching --project-dir=./advi_results -- ./myApplication
