The goal of this project is to lay out strategies and abstractions for developing lower-level system modeling and parameter tuning techniques, and for linking these to higher-level architectural and system management approaches. The project also aims to back existing post-manufacturing tuning techniques with deeper analytic methods, and to augment these one-time adjustments with more dynamic management techniques that are ongoing as the system is in use. To make the shift from very static (one-time) tuning towards very dynamic (ongoing) power-performance tuning, one needs models whose detail and abstraction vary. This allows fast, but abstract models to be used dynamically by the operating system, in order to dynamically adjust power/thermal behavior in order to stay within budget while also meeting performance goals. Microarchitectural techniques can also be employed, but likewise need to be informed by good models and measurement techniques to guide their use. The project will address these modeling issues and the associated on-the-fly management techniques.The research program pursues broad impact in several ways. First, the project has an important component for knowledge dissemination and technology transfer. The modeling and management techniques proposed in this project will be disseminated and released for free use. Building on a record of strong support for undergraduate research and underrepresented groups, the PIs will continue and broaden such activities through this collaboration. Because of the geographic proximity of CMU and Princeton, group meetings unifying the two efforts will be possible throughout the project.

该项目的目的是制定策略和摘要，以开发低级系统建模和参数调整技术，并将其链接到更高级别的体系结构和系统管理方法。该项目还旨在通过更深入的分析方法来支持现有的后期制造后调整技术，并通过随着系统的使用而持续进行的更动态的管理技术来增强这些一次性调整。为了使从非常静态的（一次性）调整转向非常动态的（正在进行的）功率绩效调整，需要细节和抽象变化的模型。这允许操作系统可以动态地使用快速但抽象的模型，以动态调整功率/热行为，以保持预算范围，同时还达到绩效目标。也可以采用微体系式技术，但同样需要通过良好的模型和测量技术来指导其使用。该项目将解决这些建模问题和相关的在线管理技术。研究计划以多种方式追求广泛的影响。首先，该项目具有知识传播和技术转移的重要组成部分。该项目中提出的建模和管理技术将被传播并免费使用。 PIS以对本科研究和代表性不足的群体的强烈支持为基础，PIS将继续通过这种合作继续并扩大此类活动。由于CMU和Princeton的地理距离，整个项目将有可能统一两项努力的小组会议。
