I am writing here to report an issue I have when using VTune to do some specific analysis.
This issue is that, when collecting data, VTune will launch my application, and stop it after about 1-2 seconds (not always at the same exact time, this is not quite deterministic) and present the results it has collected during that time, which don't represent the whole process as my application in this "test case" takes 7 seconds to run.
This problem does not occur on every analysis : I can do a Hotspots or a Memory Access analysis just fine, without VTune interrupting my application.
To make sure that this was not the problem, I changed the Collection Data Limit in the project properties to be 100 times the default value, but it did not have any impact on this issue.
I am performing these analysis on a Sandy Bridge processor, using the Sandy Bridge specific Analysis (except for Hotspots where i use the general one), and am running on Windows 7 from Visual Studio 2010.
I would be very grateful if you can give me any explanations on that, so far I have found a lot of very interesting features in VTune that could help me a lot, but those issues as well as the 2 BSODs that I have encountered thus far are setting me back a little.
