Resumé: There are technical, ecological and economic incentives, motivating the study of policies for the power management in computing systems. The main objective is to minimize the power consumption of computing devices while keeping temperature at acceptable (viable for processing units) levels. From an algorithmic perspective, we will focus on scheduling problems trying to find a trade-off between a quality of service measure (a usual scheduling objective such as the makespan, the throughput etc) and the energy consumption. The two main mechanisms that have been proposed in the literature so far are: 1) Speed scaling, where the processors may run at variable speeds based on demand and performance constraints and 2) Power down strategies, where the device can always reside in one of several states with individual power consumption rates (active, standby, and sleep states).
