For decades, computer system design and operation were driven largely by high performance objectives. Yet, as the large scale integration of semi-conductor devices is approaching its physical limits, energy efficiency and robustness have been recently promoted to first-class design constraints. Energy efficiency is mandated by the emergence of small foot-print, portable, and battery-powered computers as well as ever-increasing power density that puts stringent constraints even on computers connected to the power grid. Moreover, recent research has revealed that aggressive power management techniques can significantly increase vulnerabilities of computer systems to transient faults (soft errors) that can cause incorrect operations at run-time. These problems are even more pronounced for real-time embedded systems that must perform correctly at high reliability levels, under strict timing and energy constraints.In recent past, a number of pioneering reliability-aware power management schemes were proposed that aim at mitigating the negative effects of the popular dynamic voltage and frequency scaling. This project is addressing the conservatism of the existing solutions and developing a more general framework. Specifically, the project is devising novel solutions to achieve arbitrary reliability levels through the use of shared recovery tasks. In addition, the research is extending the framework to multiprocessor and emerging multicore platforms. The project has two major broader impact dimensions: First, energy-awareness has a direct impact on environment, economy, and society at large. Second, by promoting reliability to a first-order objective, the project will help to prevent malfunctions in safety-critical computer systems and protect property and human lives.

几十年来，计算机系统设计和操作主要由高性能目标驱动。然而，随着半导体设备的大规模整合正在接近其物理限制，最近将能源效率和鲁棒性推广到一流的设计约束。小脚印，便携式和电池供电的计算机以及不断增加的功率密度的出现，即使在连接到电网连接的计算机上也构成了严格的限制，这是由小脚印，便携式和电池供电的电脑出现的。此外，最近的研究表明，积极的电源管理技术可以显着增加计算机系统对瞬态故障（软错误）的脆弱性，这些故障可能会在运行时导致不正确的操作。对于必须在严格的时机和能量约束下必须在高可靠性水平上正确执行的实时嵌入式系统，这些问题甚至更为明显。在过去的过去，提出了许多开创性的可靠性能力管理方案，旨在减轻流行动态电压和频率扩展的负面影响。 该项目正在解决现有解决方案的保守主义，并开发更一般的框架。具体而言，该项目正在设计新颖的解决方案，以通过使用共享恢复任务来实现任意可靠性水平。此外，该研究将框架扩展到多处理器和新兴的多核心平台。 该项目具有两个更广泛的影响方面：首先，能源意识直接影响着整个环境，经济和社会。其次，通过促进一阶目标的可靠性，该项目将有助于防止安全 - 关键计算机系统中的故障并保护财产和人类生命。
