I got this message while trying to run a sampling activity -
"sampling collector failed to collect data as the sampling driver file is already in use" - is the sampling driver file same as vtuneenv.exe ?
I closed VTUNE, killed vtuneenv.exe through task manager and then ran the same sampling activity -and it ran to completion (although this time I chose the default -i.e. run the activity after closing the wizard" instead of starting and stopping it manually - can anyone give me an idea of why I would have got this message and what can be done to avoid it as I seem to get it often ?
Also, is there a way in which you can change the sampling runs after you have a completed sampling activity -for example -let's say you selected "A few sampling runs (for basic micro-architecture tuning) while configuring the samplingactivity -now that you have a sampling activity, can you go back and change to single run or multiple runs (for advanced micro-architecture tuning) or does one have to generate a new activity if we need to change the number of runs ?
