A manage-analyze-plan-execute (MAPE) loop is performed on a system-wide basis in relation to subsystems of a computing system based on one or more parameters. Performing the MAPE loop results in a performance level at which each subsystem is to operate to conserve energy utilization on the system-wide basis such that the computing system still satisfies the parameters. The subsystem the performance level at which each subsystem is to operate is communicated to the subsystem. Each subsystem operates at the performance level communicated to the subsystem.
