Sometimes, bugs in my CUDA programs cause the desktop graphics to break (in Windows).

  • 0

Sometimes, bugs in my CUDA programs cause the desktop graphics to break (in Windows). Typically, the screen remains somewhat readable, but when graphics change, such as when dragging a window, lots of semi-random colored pixels and small blocks appear.

I have tried to reset the GPU and driver by changing the desktop resolution, but that doesn’t help. The only fix I have found is to reboot the computer.

Is there a program out there or some trick I can use to get the driver and GPU to reset without rebooting?

    Edit:

    If you are on Tesla hardware on Linux and can run nvidia-smi, then you can reset the GPU using 

    nvidia-smi -r

    or 

    nvidia-smi --gpu-reset

    Here is the man output for this switch:

    Resets GPU state. Can be used to clear double bit ECC errors or
    recover hung GPU. Requires -i switch to target specific device.
    Available on Linux only.

    Otherwise…

    The way to truly reset the hardware is to reboot.

    What you describe shouldn’t happen. I recommend testing with different hardware and let us know if it still occurs.
