Find Where to Add Parallelism to Code Using the Threading Advisor - C++ Sample

Windows* OS Tutorial: HTML

Linux* OS Tutorial: HTML

Sample: <install-dir>/samples/en/C++/nqueens_Advisor

Duration: 20 minutes

Learning Objective: Demonstrates an end-to-end workflow you can ultimately apply to your own applications:
  1. Survey the target executable to locate the loops and functions where your application spends the most time.

  2. In the target sources, add Intel Advisor annotations to mark possible parallel tasks and their enclosing parallel sites.

  3. Check Suitability to predict the maximum parallel performance speedup of the target based on these annotations.

  4. Check Dependencies to predict parallel data sharing problems in the target based on these annotations.

  5. If the predicted maximum speedup benefit is worth the effort to fix the predicted parallel data sharing problems, fix the problems.

  6. Recheck Suitability to see how your fixes impact the predicted maximum speedup.

  7. If the predicted maximum speedup benefit is still worth the effort to add parallelism to the target, replace the annotations with parallel framework code that enables parallel execution.
