Profiler: Unable to collect metric and event values
I am experiencing some issues with the visual profiler (Cuda 4.1).

I am trying to profile with Nvvp a quite complex CFD code (globally a very complicated version of the particles example).
Nvvp plot the timeline but as soon i try to add a counter a got the "Metric/Event Collection Failed" error.

I used the profiler in command line and got this result: as soon i activate a counter the code became slower so the timelines
cannot coincide but the kernel order is exactly the same.

How can i fix that ?
