Wikipedia says that the Tesla M60 has 2x8 GB RAM (whatever it means) and TDP 225–300 W.

I use an EC2 instance (g3s.xlarge) which is supposed to have a Tesla M60. But nvidia-smi command says it has 8GB ram and max power limit 150W:

What does it mean? Do I get a 'half' of the card? Is the Tesla M60 actually two cards stuck together as the ram specification (2x8) suggests?

Yes, the Tesla M60 is two GPUs stuck together, and each g3s.xlarge or g3.4xlarge instance gets one of the two GPUs.

  • BTW, what does 's' stand for in 'g3s'? Other 'g3' machines don't have it. – hans Mar 12 '19 at 15:46
  • @hans Probably something like "small". That instance type has far less CPU and RAM than the other instance types. – Michael Hampton Mar 12 '19 at 15:47

    @MichaelHampton How can it both be small and xlarge at the same time? – kasperd Mar 24 '19 at 7:49

    @kasperd You'll have to ask Amazon. I don't understand their naming conventions either. – Michael Hampton Mar 24 '19 at 15:12
