摘要:

由于低功耗和高性能的要求,动态资源管理已成为现代计算机和通信系统设计的主要研究领域之一。集成核心的数量、异构程度和控制旋钮的数量稳步增加。因此,系统复杂性的增长速度超过了我们优化和动态管理资源的能力。此外,离线方法是次优的,由于工作负载的变化和大量的新的应用程序在设计时未知的。本文首先回顾了最近用于预测系统性能、功率和温度的在线学习技术。然后,我们描述了使用预测模型在线控制使用两种现代方法:模仿学习(IL)和显式非线性模型预测控制(NMPC)。商业移动平台上的16个基准测试结果表明,IL方法成功地适应控制策略未知的应用程序。与现代GPU子系统的多变量电源管理的最先进算法相比,显式NMPC可节省25%的能源。

英文摘要:

Dynamic resource management has become one of the major areas of research in modern computer and communication system design due to lower power consumption and higher performance demands. The number of integrated cores, level of heterogeneity and amount of control knobs increase steadily. As a result, the system complexity is increasing faster than our ability to optimize and dynamically manage the resources. Moreover, offline approaches are sub-optimal due to workload variations and large volume of new applications unknown at design time. This paper first reviews recent online learning techniques for predicting system performance, power, and temperature. Then, we describe the use of predictive models for online control using two modern approaches: imitation learning (IL) and an explicit nonlinear model predictive control (NMPC). Evaluations on a commercial mobile platform with 16 benchmarks show that the IL approach successfully adapts the control policy to unknown applications. The explicit NMPC provides 25% energy savings compared to a state-of-the-art algorithm for multi-variable power management of modern GPU sub-systems.
