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.

该项目的目标是制定策略和抽象，用于开发较低级别的系统建模和参数调整技术，并将这些技术与较高级别的体系结构和系统管理方法联系起来。该项目还旨在通过更深入的分析方法支持现有的制造后调整技术，并通过在系统使用过程中持续进行的更动态的管理技术来增强这些一次性调整。为了从非常静态（一次性）调整转向非常动态（持续）的功率性能调整，需要细节和抽象各不相同的模型。这允许操作系统动态使用快速但抽象的模型，以便动态调整功率/热行为，以保持在预算范围内，同时满足性能目标。也可以采用微架构技术，但同样需要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动态管理技术。该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让的重要组成部分。本项目提出的建模和管理技术将被传播并免费使用。基于对本科生研究和代表性不足群体的大力支持，PI 将通过此次合作继续并扩大此类活动。由于卡内基梅隆大学和普林斯顿大学地理位置接近，因此在整个项目中可以召开小组会议来统一两项工作。
