Optimizing GPU Settings (P2 and G3 Instances Only)

There are several GPU setting optimizations that you can perform to achieve the best performance on P2 and G3 instances. By default, the NVIDIA driver uses an autoboost feature, which varies the GPU clock speeds. By disabling the autoboost feature and setting the GPU clock speeds to their maximum frequency, you can consistently achieve the maximum performance with your P2 and G3 instances.

To optimize P2 or G3 GPU settings

  1. Open a PowerShell window and navigate to the NVIDIA installation folder.

    Copy
    cd "C:\Program Files\NVIDIA Corporation\NVSMI"
  2. Disable the autoboost feature for all GPUs on the instance.

    Copy
    .\nvidia-smi --auto-boost-default=0
  3. Set all GPU clock speeds to their maximum frequency. Use the memory and graphics clock speeds listed below.

    • For P2 instances: 2505,875

    • For G3 instances: 2505,1177

    Copy
    .\nvidia-smi -ac "2505,1177"
