How should GPU energy use be estimated?

[adrianco]

Outline Action Item Details

We have a reasonable handle on CPU energy use by taking CPU utilization and mapping it to an energy curve driven by the Thermal Design Power (TDP) of a package - which is sometimes the only public data that is available. GPUs are becoming more common, have a higher TDP than CPUs, but we don't have an easy or standard way to measure the utilization of the GPUs in a system. Propose to reach out to contacts at NVIDIA to see if we can find some answers and encourage them to join GSF.
