Non-preemptive Speed Scaling
We consider the following variant of the speed scaling problem introduced by Yao, Demers, and Shenker. We are given a set of jobs and we have a variable-speed processor to process them. The higher the processor speed, the higher the energy consumption. Each job is associated with its own release time, deadline, and processing volume. The objective is to find a feasible schedule that minimizes t...
متن کاملSpeed-Scaling with No Preemptions
We revisit the non-preemptive speed-scaling problem, in which a set of jobs have to be executed on a single or a set of parallel speed-scalable processor(s) between their release dates and deadlines so that the energy consumption to be minimized. We adopt the speedscaling mechanism first introduced in [Yao et al., FOCS 1995] according to which the power dissipated is a convex function of the pr...
متن کاملSpeed scaling: An algorithmic perspective
Speed scaling has long been used as a power-saving mechanism at a chip level. However, in recent years, speed scaling has begun to be used as an approach for trading off energy usage and performance throughout all levels of computer systems. This wide-spread use of speed scaling has motivated significant research on the topic, but many fundamental questions about speed scaling are only beginnin...
متن کاملSpeed Scaling to Manage Temperature
We consider the speed scaling problem where the quality of service objective is deadline feasibility and the power objective is temperature. In the case of batched jobs, we give a simple algorithm to compute the optimal schedule. For general instances, we give a new online algorithm, and obtain an upper bound on the competitive ratio of this algorithm that is an order of magnitude better than t...
متن کاملAlgorithms for Dynamic Speed Scaling
Many modern microprocessors allow the speed/frequency to be set dynamically. The general goal is to execute a sequence of jobs on a variable-speed processor so as to minimize energy consumption. This paper surveys algorithmic results on dynamic speed scaling. We address settings where (1) jobs have strict deadlines and (2) job flow times are to be minimized. 2010 Mathematics Subject Classificat...
