I need some ressources that illustrates the sleep mode that the GPU enter when no work is given, because I can see this with nvidia-smi but no documentation about this.
For example, for my tesla M2075, it passes from 75W to 28W (diff=47W). This GPU (fermi) is a bit old but in the fermi whitepaper I don’t find any information about this .
I can estimate that there is the impact of launching the nvidia-smi! Even though, the idle of this GPU is ~= 56W so (diff=18W).
