I don't think it is possible to look up the computation utilization of
the GTX cards or at least I haven't figured out how to. You can look
up the GPU memory utilization, temperature, fan speed, etc. with
nvidia-smi. We have found CPU utilization, GPU fan speed and (to a
lesser extent) temperature to be reasonable surrogates for GPU
utilization. We are still not using Kaldi nnet code at Edinburgh due
to the inertia of changing the experimental setups, and so have no
stats to share.
