CAREER: Self-Regulating Power-Aware Interconnection Networks

在许多数字系统中，从个人电脑和服务器到互联网路由器和嵌入式系统，电力正变得越来越重要，如果不是比性能更重要的话。虽然已经有大量研究探索数字系统的处理和存储元件的功率效率，但调查通信元件的功率消耗的研究一直滞后。随着各种数字系统互联程度的不断提高，探索功率感知互联网络已成为当务之急。在这份计划中，我们概述了我们的计划，即研究、开发和建立自我调节的功率感知互联网络，在满足设计约束的同时自动权衡功率和性能。在这些网络中，功率感知型路由器和链路机制输出旋钮，可以通过这些旋钮来调整网络功率和性能。然后，策略控制这些旋钮，以提供满足设计目标的网络功率性能。自我调节的功率感知网络使设计者从协调两个高度不同的目标-高性能和低功耗-的艰巨任务中解脱出来。在强调和展示功率感知在网络中的重要性的过程中，我们提出的研究从一个新的角度推进了对网络的更深层次的理解，可能在研究中做出重大贡献。此外，我们认为我们的能效研究是网络课程不可或缺的一部分。

Power is becoming increasingly as important, if not more important than performance in many digital systems ranging from PCs and servers to Internet routers and embedded systems-on-a-chip. While there has been substantial research exploring the power efficiency of the processing and memory elements of digital systems, research investigating the powerconsumption of communication elements has been lagging. As a wide range of digital systems becomes increasingly interconnected, it is nowboth timely and critical to explore power-aware interconnection networks.In this proposal, we outline our plans to research, develop and build self-regulating power-aware interconnection networks that trade off power and performance automatically while meeting design constraints. In these networks, power-aware router and link mechanisms export knobs by which network power and performance can be adjusted. Policies then control these knobs to deliver network power-performance that meet design goals. Self-regulating power-aware networks alleviate designers from the daunting task of reconciling two highly divergent goals -high performance, and low power.In highlighting and demonstrating the importance of power awareness in networks, our proposed research advances a deeper understanding of networks from a fresh perspective, with a potential for high-impact contributions in research. In addition, we see our research leading to power efficiency being an integral part of networking curriculum.
