→vTune Amplifier with OpenMP (Alex)
[[File:Ascii_art_parallel_threads.png]]
Note the pink section on the master thread. That section represents OpenCV initializing the window the resulting video is displayed on. This is outside the scope of our code so we assume that it is uncontrollable overhead.
The orange blocks show the parallel regions where we process and convert each frame and the gap between is the task where OpenCV grabs each individual frame from the source.
Then we ran our code through the HPC Performance Characterization analysis to verify the efficiency of our OpenMP implementation.
