I had installed an old vTune version on Windows XP running on a Pentium D processor. VTune is version 5.0
I've run VTunedemo under VTune and I'm getting mixed results.
1) Sampling does not work properly. I get "The Monitor Session cannot start because you have requested a buffer of 512K. Please reduce this allocation and try again. RC = 3". Lowering the buffer value does not make this error go away.
2) Win32* Call Graph Profiling seems to work but I don't have a Win2K machine readily available wherein I can double check the results I'm getting on the WinXP machine.
I think VTune 5.0 came out way before WinXP, so how does this affect the accuracy of VTune running on an unsupported OS?
