Abstract

Despite the extensive literature on energy efficient control mechanisms for servers, only few studies address the processor sharing discipline. We study the energy-performance trade-off in an energy-aware MX/G/1-PS system using two popular cost metrics. Among a family of control policies that can possibly stay idle before going to sleep to save energy, the optimal policy is found to be a simple control that either leaves the server idle, or puts it to sleep immediately whenever it becomes idle.
