Using nvidia-smi to get information on GPU Cards

NVIDIA’s System Management Interface (nvidia-smi) is a useful tool to manipulate and control the GPU Cards. There are a few use case listed here

1. Listing of NVIDIA GPU Cards

# nvidia-smi -L

GPU 0: Tesla M2070 (S/N: 03212xxxxxxxx)
GPU 1: Tesla M2070 (S/N: 03212yyyyyyyy)

2. Display GPU information

# nvidia-smi -i 0 -q
