https://community.intel.com/t5/Analyzers/Performance-Counters/m-p/938482#M7463 VTune uses statistic sampling for event counting. It means that every run gives different values. Is it possible to get an exact counting of events in each procedure ? If yes, how to do this ? Regards.

Using call graph you can get timing information per function, but even that includes some variableness.<BR /><BR />Regards, Thu, 06 Apr 2006 08:19:10 GMT https://community.intel.com/t5/Analyzers/Performance-Counters/m-p/938483#M7464 David_A_Intel1 2006-04-06T08:19:10Z
