A power management system may provide power management recommendations to a computer system including a plurality of computing nodes (which may include processors, etc.), to cause the computing nodes to individually or collectively adjust power states or modes of respective processors to achieve power management of the computer system. The power management system may be provided with a power management framework that continuously utilizes direct and indirect service-level feedbacks to guide power management decisions. The power management system may employ a reinforcement learning algorithm to make power management decisions at a user level, and provide a fast decision overriding mechanism for platform events or service-requested performance boosts.
