→Vtune Profiler in Practice
[[File:Hot Spot Results.png]]
Here we have the Hot Spots in our code and since it is a relatively simple application and we only have one main function that makes up a majority of CPU usage time. If we were to utilize the Vtune Profiler on a more complex application we would definitely see other functions and more interesting results overall.

This is our Flame Graph here and again since we have a simple application which only ran for 10 seconds there is little to see. What we can see is that we have 3 chunks of CPU usage throughout the lifetime of the application. Our first chunk appears to be the initialization of the code and functions to start the code running. The second chunk shows the Concurrency Runtime algorithm being executing the is_prime function, similarly in the final chunk we see the OMP version of the is_prime function.
