SHF: Medium: Automatic Control Driven Resource Management in Chip Multiprocessors

未来的计算机体系结构将执行从气候建模到生物信息学再到新材料模拟的关键应用。新兴的芯片多处理器是提供高性能和低功耗的新型体系结构。当多个应用程序共享同一芯片多处理器时，体系结构资源的适当管理成为一个关键问题。这项研究的目标是利用形式反馈控制理论中的稳健和弹性技术对芯片多处理器中发现的不同类型的资源进行应用间管理。它使应用程序能够满足其性能要求，同时最大限度地利用硬件资源。这项研究有助于更顺利地从传统架构过渡到芯片多处理器，从而最大限度地增加可以利用这些新兴架构的关键应用程序的数量。将正在开发的技术转移到IBM和惠普实验室，允许在由芯片多处理器构建的大规模体系结构中对所建议的策略进行认真测试。这个项目的结果不仅在一个新的领域提供了反馈控制理论的准确评估，而且还集成到了两个重要的软件基础设施中，Singulity和Xen，这两个基础设施都被大型研究社区广泛使用。这项研究还包括两项扩大参与的努力，即工程周末访问(VIEW)和美国航天局-航空航天教育服务项目(NASA-AESP)在科学和学校中心(CSATS)。

Future computer architectures will execute critical applications ranging from climate modeling to bioinformatics to simulations of new materials. Emerging chip multiprocessors are novel architectures that provide high performance and low power consumption. When multiple applications share the same chip multiprocessor, proper management of architectural resources becomes a critical problem. This research targets inter-application management of different types of resources found in a chip multiprocessor using robust and resilient techniques drawn from formal feedback control theory. It enables applications to satisfy their performance requirements and, at the same time, maximizes the utilization of hardware resources. This research helps to make the transition from conventional architectures to chip multiprocessors smoother, and as a result, maximizes the number of critical applications that can take advantage of these emerging architectures. The transfer of the technology being developed to IBM and HP Labs allows serious testing of the proposed strategies in large-scale architectures built from chip multiprocessors. The results from this project not only present an accurate assessment of feedback control theory in a new domain, but also get integrated into two important software infrastructures, Singularity and Xen, both used extensively by large research communities. This research also accommodates two efforts in broadening participation, CISE Visit in Engineering Weekends (VIEW) and NASA-Aerospace Education Services Project (NASA-AESP) at the Center for Science and the Schools (CSATS).
