本文介绍了我们的应用感知电源管理方法。我们结合了对关键工作负载指标的持续监控、在线电源和性能模型使用情况以及及时的p状态控制,以实现应用感知电源管理。通过我们的方法,我们提出了两个新的电源管理解决方案:PerformanceMaximizer(PM)在指定的电源限制下找到可能的最佳性能,而PowerSave(PS)在保持高于指定要求的性能的同时节省能源。我们在奔腾M平台上使用SPEC-CPU2000套件对这两种情况进行了评估,讨论了工作负载特征的影响以及了解工作负载的好处
This paper presents our approach for application-aware power management. We combine continuous monitoring of critical workload indicators, online power and performance model usage and timely p-state control to realize application-aware power management. We present two new power management solutions enabled by our methodology: PerformanceMaximizer (PM) finds the best possible performance under specified power constraints and PowerSave (PS) saves energy while keeping performance above specified requirements. We evaluate both using the SPEC-CPU2000 suite on a Pentium M platform discussing implications of workload characteristics and benefits of being workload-aware
