nvidia-smi (also NVSMI) provides monitoring and management capabilities for each of NVIDIA's Tesla, Quadro, GRID and GeForce GPU device from Fermi and higher architecture families. The following steps can be used to access nVidia-smi and monitor GPU usage for TUFLOW simulations:

Accessing nvidia-smi to review GPU Usage

  1. Launch the DOS Command Prompt from the Run window (press Win+R on your keyboard to open it then, type cmd).
