wfawfIf we double click on this function we it will shows the sources code and shows you which line of the code actually use the most time in the specific function. Now we can tell that most of the time are spend on the while loop.

wfawfTo compare a paralleled version of this code I already have a program that use CILK PLUS to parallelize that program. Below is the link to download that code. Simply replace the ''find_hotspots.cpp'' with this code, build it and run the Analysis again. Link:[[File:Find hotspots.zip]]
