National Science FoundationDistributed Systems Research CISE/CNSABSTRACTPROPOSAL NUMBER: 0411127PRINCIPAL INVESTIGATOR: Dwarkadas, SandhyaINSTITUTION: University of RochesterPROPOSAL TITLE: Operating System Strategies for Energy- and Re-source-Aware AdaptationWith increases in device capabilities, energy consumption has emerged as a large and growing concern for both mobile and server-class computers. Hard-ware designers have responded by developing devices (e.g. hard disks and net-works) that can be "powered down" (dropped into a non-operational mode) when inactive, and other devices (e.g. processor components) that can be "scaled back" (by reducing voltage or reallocating in part to other threads), to operate below their peak performance and power. To utilize such devices effectively, the operating system must dynamically "shape" the offered load. For "power down" devices it should aim for burstiness, to maximize the length of low-power inter-vals and minimize the number of costly state transitions. For "scale back" de-vices it should aim for smoothness, to leverage the nonlinear dependence of power on voltage and to avoid paying for unutilized resources. For devices with both capabilities it must balance the benefits of the two approaches.Work is addressing both existing and emerging architectures, including single-threaded, multi-threaded, and clustered processors. Expected results include (1) the characterization of server and mobile workloads in terms of behavior variability and (2) scheduler and device management strategies that combine run-time instrumentation with profiles of past behavior to model the needs of all running applications, and to match those needs to available resources. Dis-semination will be achieved via publications, students, open source software tools, and/or industry collaboration. Broader impacts will include the re-source-aware adaptation of future increasingly complex systems for improved performance and reduced energy.Dr. Brett D.

国家科学基金会分布式系统研究CISE/CNSABSTRACTPROPOSAL编号：0411127主要开发者：Dwarkadas，SandhyaInstitution：University of Rochester PROPOSAL标题：Operating System Strategies for Energy- and Re-source-Aware Adaptation随着设备功能的增加，能耗已成为移动的和服务器级计算机的一个大问题，并且日益受到关注。硬件设计者已经通过开发当不活动时可以“断电”（进入非操作模式）的设备（例如硬盘和网络）以及可以“缩减”（通过降低电压或部分地重新分配给其他线程）的其他设备（例如处理器组件）来响应，以在其峰值性能和功率以下操作。 为了有效地利用这些设备，操作系统必须动态地“塑造”所提供的负载。 对于“掉电”设备，它应该以突发性为目标，以最大化低功耗间隔的长度，并最小化昂贵的状态转换的数量。 对于“缩减”设备，它应该以平滑为目标，利用功率对电压的非线性依赖，并避免为未利用的资源付费。 对于具有这两种功能的设备，它必须平衡这两种方法的优点。工作正在解决现有和新兴的架构，包括单线程、多线程和集群处理器。 预期的结果包括：（1）服务器和移动的工作负载在行为可变性方面的特征，以及（2）将联合收割机运行时插装与过去行为的配置文件相结合的调度器和设备管理策略，以模拟所有正在运行的应用程序的需求，并将这些需求与可用资源相匹配。 传播将通过出版物，学生，开源软件工具和/或行业合作来实现。 更广泛的影响将包括对未来日益复杂的系统的资源意识适应，以提高性能和降低能耗。Fleisch Program Director，CISE/CNS 2004年6月16日
