how to get utilization rates of gpu? (nvml)

I need gpu information for my cuda project test.

I am using nvml library, and I successfully get temperature information. But, nvml reports ERROR_NOT_SUPPORTED in nvmlDeviceGetUtilizationRates().

So now, how to get utilization rates of gpu? Clearly, there will be a way like NVIDIA GeForce Experience.

thanks,

p.s. oops! I am insufficient reputation... If you want to see NVIDIA GeForce Experience example image, click this link.

Solution

  • Maybe your graphics card, the GTX Titan (based on your image) simply does not support volatile GPU utilization?
    I think this functionality is only supported on Quadro and Tesla cards.

    Additionally, can you show how you use nvml in your code?
