To decrease power use and cooling costs of our systems, we need more adaptive on-node systems in order to optimize the available resources. Current options available require setting options for power use ahead of time or reliance on kernel-level governors. We can do better. Charles Darwin once said that “Intelligence is based on how efficient a species became at doing the things they need to survive.” By this definition, most of our systems are primitive and wasting many resources, consuming calories that they do not need and throwing them off as heat energy, which we then have to consume more calories to remediate in our datacenters. In this talk, we give a vision of more adaptive power-tuning models. We will use a combination of TuneD and the Kubernetes Power manager to demonstrate a model of how we can design more intelligent systems.
