Metric Description
Potential Gain shows the maximum time that could be saved if the OpenMP* region is optimized to have no load imbalance assuming no runtime overhead (OpenMP Region Time minus Region Ideal Time). If the Potential Gain is large, make sure the workload for this region is enough and the loop schedule is optimal.
VTune Amplifier uses the following methodology to calculate the Potential Gain metric that is a sum of inefficiencies normalized by the number of threads:
