Intel Vectorization Toolkit: Step 2. Determine Hotspots Using Intel® VTune™ Amplifier XE

You can use Intel® VTune™ Amplifier XE, our performance profiler, to find the most time-consuming functions in your application.  The "Hotspots" analysis type is recommended, although "Lightweight Hotspots" would work as well (it will profile the whole system as opposed to just your application).   Identifying which areas of your code are taking the most time will allow you to focus your optimization efforts in the areas where performance improvements will have the most effect.  Generally you want to focus on only the top few hotspots, or functions taking at least 10% of your application's total time.  Make note of the hotspots you want to focus on for the next step.
