Reduce Parallel Overhead, Lock Contention, and Enable Chunking
The data collected and analyzed in the Suitability Report window shows data for the selected site. The text that appears below Runtime impact for this site (lower-right area) may recommend that you consider reducing several types of parallel overhead, lock contention, and enable chunking in your parallel program, as explained in Suitability Report Overview. If you agree to address a category later by using the chosen parallel framework's capabilities or by tuning the parallel code after you have implemented parallelism, check that category.
This group of topics explain site, task, and lock overhead, lock contention, and task chunking.
