My NVidia Quattro 600 GPU is functioning correctly, but running nvidia-smi.exe displays "Insufficient Permissions".
I am executing the command in Administrator Mode, and the drivers are all up to date.
How can I fix the permission's problem?
Running the test mentioned in How to verify the usage of the GPU?, I get that I am "running on CPU". (Fiddling with the GPU because I am trying to run the CNTK examples.)
Turns out that the GPU can't be used to simultaneously do graphics rendering and calculations; for this I'd need a dedicated GPU that doesn't support the monitors at the same time.
