Kindly please if you could help me in this issue?
I have a code which conatins functions that take nano-seconds, I want to know if the vtune can profile it or not?
what is the resolution of vtune?
Thanks a lot,Hoda
You have options to increase the sampling rate (probably with some influence on performance). My experience may not be relevant, but I suspect you will need run times of at least 10 seconds with each function you want to profile totalling at least 5%, to get useful results.
Till I know you can get to a minimum of 1ms sample rate. Also, it is suggested to run your critical function in a loop to get a larger execution time and then do sampling.
Direct link to the same problem.
Time resolution of VTune is around 3ms.
