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.
Start cooking your performance analysis with understanding tuning techniques, performance metrics and hardware solutions for collecting statistics. After that you can drill down to particular tuning or configuration recipes provided for the Intel® VTune™ Amplifier.
