CSR-EHS: Analytical Techniques for Global Energy Minimization of a System of Interacting Components

基于摩尔定律的晶体管数量翻倍和特征尺寸的减小导致了性能的显著提高，但代价是功耗呈指数级增长，从而产生热量。除非开发出电力和热管理的系统级解决方案，否则根据摩尔定律进行的扩展将无法继续。包括动态电源管理(DPM)和动态电压频率调节(DVFS)在内的系统级功率优化的现有技术以零碎方式运行，并且通常是次优的。到目前为止，热管理方案也相当简单，并且不与控制功耗从而控制热产生的DPM或DVFS策略交互。这项研究将为多组件计算平台的能量和热管理提供统一的框架。该框架将围绕适用于多个计算系统抽象层次的一般性问题表述的最佳分析解决方案而建立。抽象层次包括板级、多处理器系统级和微体系结构流水线级。这里开发的能源和热管理战略将降低包装和冷却成本，并延长所有计算系统的寿命--从便携式设备到高性能台式机再到服务器。此外，这项研究将在微电子系统的能量管理以及电子和非电子部件的热管理的不同领域对学生进行培训。

Moore's law based doubling of transistor counts and decreasing feature sizes have resulted in a phenomenal increase in performance at the expense of an exponential increase in power consumptionand consequently, heat generation. Scaling according to Moore's law cannot continue unless system-level solutions for power and thermal management are developed. Existing techniques for system-levelpower optimization including dynamic power management (DPM) and dynamic voltage frequency scaling (DVFS) operate in a piece-meal fashion and are sub-optimal in general. Thermal management schemes, to date, are also fairly simple and do not interact with DPM or DVFS policies that control the power consumption and therefore heat generation.This research will provide a unified framework for energy and thermal management of multi-component computing platforms. The framework will be built around optimal analytical solutions to genericproblem formulations that will be applicable at multiple levels of computing system abstraction. The abstraction levels will include board level, multi-processor system-on-chip level and micro-architecturepipeline level. The energy and thermal management strategies developed here will reduce the packaging and cooling costs and increase the lifetime of all computing systems -- from portable devices to highperformance desktops to servers. Furthermore, this research will train students in the diverse fields of energy management of microelectronic systems and thermal management of electronic and non-electronic components.
