I have posted the same question on StackOverflow. cuda - How to specify nvprof "devices" option for Nvidia Visual Profiler? - Stack Overflow
CUDA Toolkit 9.0, Windows 10, GTX 1060 & NVS 315, 385.54 Driver version.
Nvidia Visual Profiler always fails to profile, returning the following two warning messages:
“Warning: This version of nvprof doesn’t support the underlying device, GPU profiling skipped”
“Warning: No CUDA application was profiled, exiting”
Note my machine has two GPUs installed. Physically removing the NVS 315 fixes the problem; Visual Profiler works. I only want to profile the GTX 1060, but I want to do so with the NVS 315 installed.
Using nvprof and specifying the “–devices” option works:
C:>nvprof --devices 0 bandwidthTest.exe
Whereas
C:>nvprof --devices 1 bandwidthTest.exe
======== Warning: This version of nvprof doesn’t support the underlying device, GPU profiling skipped
Exporting the results from nvprof, then opening in Visual Profiler works:
C:>nvprof --devices 0 --export-profile results.nvvp bandwidthTest.exe
But I’m lazy and don’t want to repeat this a hundred times every time I profile.
So it seems there is something about the NVS 315 that is incompatible. Furthermore, specifying something like “–devices 0” to Visual Profiler (nvvp) would seem to be a solution. If only I knew how.
