Abstract: Coordinating dynamic power scaling of agents based on power correlations of agent instructions is disclosed. A global power controller determines a first local power quantifier of a first agent executing an agent instruction of a task of a workload. The global power controller stores a correlation between the first agent executing the agent instruction and a second local power quantifier corresponding to a second agent. The global power controller subsequently determines that the first agent is executing or will execute the agent instruction. The global power controller accesses the correlation associated with the first agent executing the agent instruction and sends to the second agent a proposed power level based on the correlation.
