II-NEW: A Platform to Advance Research in Energy-Efficient Computing

计算功耗是提高计算系统性能的最困难和最普遍的挑战。该项目旨在收购基于低功耗片上系统（SoC）处理器节点的新型集群计算系统。与传统服务器相比，这种新型服务器有望大幅提高每瓦吞吐量。 该项目利用收购的基础设施，探索这类新服务器对应用程序工作负载的性能、能耗和热特性的影响。分析不同类型并行工作负载的结果，以了解应用程序特性和系统架构之间的相互作用，以及这些相互作用对性能和功耗的影响。该项目还调查了这种新型服务器对电源和热管理技术有效性的影响。拟议的基础设施，使追求新的研究方向的计算系统的能源效率。该项目的成果将在主要研究场所传播，使计算界能够更好地了解新兴的低功耗SoC系统对计算集群能效的影响。 这个项目的更广泛的影响，包括推广到当地高中学生在普罗维登斯，RI，和研究经验的本科生在布朗大学。

Computing power consumption is the most difficult and pervasive challenge towards improving the performance of computing systems. This project seeks the acquisition of a new class of cluster computing systems based on low-power System-on-a-Chip (SoC) processor nodes. Compared to traditional servers, this new class of servers promises large improvements in throughput per Watt. Using the acquired infrastructure, the project explores the ramifications of this new class of servers on the performance, energy consumption and thermal characteristics of application workloads. The results from different types of parallel workloads are analyzed to understand the interactions between application characteristics and system architecture and the impact of these interactions on performance and power consumption. The project also investigates the impact of this new class of servers on the effectiveness of power and thermal management techniques. The proposed infrastructure enables the pursuit of new research directions in energy-efficiency of computing systems. The results of this project will be disseminated in premier research venues, enabling the computing community to better understand the impact of emerging low-power SoC-based systems on the energy efficiency of computing clusters. The broader impacts of this project include outreach to local high school students in Providence, RI, and research experiences for undergraduate students at Brown University.
