许多应用领域，例如需求响应、能源核算或能源感知调度，都需要对计算机系统的能源消耗进行估计。然而，现有的评估方法通常对可接受的设置时或运行时的工作量做出限制性假设，它们是为特定的硬件或软件量身定制的，或者它们不能为评估提供准确性保证。本文介绍了一种计算机能量估算框架FRESCO。FRESCO是一个灵活的框架，用于估计各种计算机系统的能耗。特别是，FRESCO考虑硬件制造商的技术信息，系统规范，如平均负载，在运行时采样的信息，例如，CPU在特定状态下花费的时间，以及可能在设置时了解到的能耗配置文件。根据精度要求和可用信息，FRESCO部署并执行适当的估算器。我们用三个真实的用例评估了FRESCO。我们的评估表明，FRESCO为广泛的分析方案提供了有意义的估计。
Many application areas, e.g., demand response, energy accounting or energy-aware scheduling, require estimates of the energy consumption of computer systems. However, existing estimation approaches often make restrictive assumptions regarding the effort at setup time or run time that is acceptable, they are tailored for specific hardware or software, or they cannot provide accuracy guarantees for the estimates. In this paper, we introduce FRESCO, a FRamework for the Energy eStimation of COmputers. FRESCO is a flexible framework for the estimation of the energy consumption of a wide range of computer systems. In particular, FRESCO considers technical information of the hardware manufacturer, system specifications like the average load, information that have been sampled at run time, e.g., the time the CPU spent in a specific state, and energy consumption profiles that might have been learned at setup time. Based on accuracy requirements and information available, FRESCO deploys and executes appropriate estimators. We have evaluated FRESCO with three real-world use cases. Our evaluation shows that FRESCO produces meaningful estimates for a wide range of analytical scenarios.
