title: Google Cloud tesla K80, only one device showing up?
body: <p>I've setup an instance on Google Cloud with the following specs:
  4 vCPUs, 15 GB memory, 1 Tesla K80 GPU</p>
  
  <p>Tesla K80 consists of 2 GPU units and each should show up as a separate device in the nvidia's logs. However, when I run nvidia-smi in the shell it shows only one.

  <p>Does anyone know how to solve this issue? Is this because my cloud GPU quota is one and hence only one device is being used?</p>
