Does anyone has any experience with running VTune in a virtualized environment ? I have OSX and I am running Windows 8 under VMware Fusion with Intel Parallel Studio XE 2013 installed on it. VMware fusion does have an option so that profiling tools like VTune work on it. Therefore, VTune works on this setup.
I would like to know if those results are reliable. For instance, I have been surprised to find out that from run to run a small microbenchmark code always take the same timing under OSX (with variation under 5% for a timing of 0.5s). Under Fusion/Windows, VTune gives me a variation of time of around 20% from run to run ! But this variation disapears completly with some "real code" that takes around 13s to run. Therefore, I am puzzled with the reliability of VTune in a virtualized environment. Does anyone has some experience with that ?
