This recipe introduces a flow to analyze CPU utilization of your OpenMP* or hybrid OpenMP-MPI application and identify causes of possible inefficiencies.
OpenMP* Imbalance and Scheduling Overhead from Intel® VTune™ Amplifier Performance Analysis Cookbook
This recipe shows how to detect and fix frequent parallel bottlenecks of OpenMP programs such as imbalance on barriers and scheduling overhead.
Processor Cores Underutilization: OpenMP* Serial Time from Intel® VTune™ Amplifier Performance Analysis Cookbook
This recipe shows how to identify a fraction of serial execution in an application parallelized with OpenMP, discover additional opportunities for parallelization, and improve scalability of the application.
