The Art of Profiling Using Intel VTune Amplifier, Part 4

In previous parts of this series, I discussed how to set up a VTune Basic Hotspots analysis to profile the target program. By quickly going through the program, you would notice that there is a significant loop at line 88 in the gen_pswd function. Therefore, one might think that gen_pswd is the hotspot. However, the results reported by VTune says otherwise. Make sure that you are on the Hotspots by CPU Usage viewpoint to follow this article. Continue reading
