Cuda reset utility

Using Cuda with openGL interop on Windows

If I make a programming error I’m left with a corrupted screen with a few random ‘snow’ pixels then
as I move the window in a few apps (especially vs2010) the snow increases until the display is unusable

The only solution I have found is to reboot the machine - which is getting a bit tedious.

Is there a CUDA reset utility that will restart the driver or flush the GPU memory?
