摘要

我们提出了一种新的企业系统DVFS算法，它将性能提升为一阶控制参数，并将频率和电压作为性能要求的函数进行管理。我们在Linux下的真实英特尔Westmere平台上实现了我们的算法，并证明了它能够将目标性能的标准偏差降低90%以上，同时将平均功耗降低17%。

OS-level power minimization under tight performance constraints in general purpose systems

We propose a new DVFS algorithm for enterprise systems that elevates performance as a first order control parameter and manages frequency and voltage as a function of performance requirements. We implement our algorithm on real Intel Westmere platform in Linux and demonstrate its ability to reduce the standard deviation from target performance by more than 90% over state of the art policies while reducing average power by 17%.
