Enabling environmentally sustainable data center systems while supporting escalating computing needs has emerged as a “grand challenge” of our times. Unfortunately, reducing emissions is especially challenging for modern data center applications, since their design often prioritizes performance and scalability, causing increased emissions from (1) performing extraneous work and (2) requiring more computing hardware. To reduce emissions while achieving performance and scalability goals, this project will leverage data-driven techniques to radically rethink the cross-layer hardware-software data center computing stack from the ground-up, with carbon efficiency at the forefront. This project also includes a comprehensive education and outreach plan that is seamlessly integrated with the research. The highlights include: (a) adding new sustainability modules in high school, undergraduate, and graduate curricula; (b) conducting sustainability-focused workshops and tutorials at academic conferences; and (c) engaging students from underrepresented groups in sustainability research. Thus, this project’s direct impact is reducing carbon emissions to combat climate change by redefining how future data center systems are designed, managed, and taught in a sustainability-first manner.Aiming at reducing emissions caused by microservices, this project systematically studies microservices through a sustainability lens. The project’s key innovation is a radically redesigned hardware-software systems stack with carbon-aware hardware and novel software systems that leverage such hardware while achieving microservices' scalability goals. On the hardware front, this work will take a new approach using the sustainability principles of reducing and reusing to systematically design carbon-aware hardware at the server, device component, and microarchitecture levels. First, this work will identify when to reuse older servers to run latency-tolerant microservices. Second, to reduce devices, this work will develop a tool to only accelerate key common primitives and analyze resource wastage to design reduced components. Third, this work will design leaner microarchitectures. On the software front, this work will develop a novel carbon-aware data-driven resource management framework to enable the carbon-efficient designs at each hardware level. By pursuing data-driven techniques, this work will highlight the value of using data centers' always-on telemetry to achieve its designs. This cross-disciplinary research cuts across three areas: computer architecture, software systems, and new application paradigms, opening new opportunities for interdisciplinary work on sustainable computing.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在支持不断增长的计算需求的同时实现环境可持续的数据中心系统已成为我们这个时代的“重大挑战”，不幸的是，减少排放对于现代数据中心应用来说尤其具有挑战性，因为它们的设计通常优先考虑性能和可扩展性，从而导致以下方面的排放增加： 1) 执行无关的工作；(2) 需要更多的计算硬件，以减少排放，同时实现性能和可扩展性目标，该项目将利用数据驱动技术从根本上重新思考跨层硬件-软件数据中心计算堆栈。向上，该项目还包括与研究无缝结合的综合教育和推广计划，重点包括：(a) 在高中、本科生和研究生课程中添加新的可持续发展模块；在学术会议上举办以可持续发展为重点的研讨会和教程；(c) 让代表性不足的群体的学生参与可持续发展研究，因此，该项目的直接影响是通过重新定义未来数据中心系统的设计、管理和使用方式来减少碳排放，以应对气候变化。教于该项目旨在减少微服务造成的排放，通过可持续发展的视角系统地研究微服务。该项目的关键创新是彻底重新设计的硬件-软件系统堆栈，其中包含碳感知硬件和利用此类硬件的新颖软件系统。在硬件方面，这项工作将采用一种新的方法，利用减少和重用的可持续性原则，在服务器、设备组件和微架构级别系统地设计碳感知硬件。这项工作将确定何时重用旧服务器来运行容忍延迟的微服务。其次，为了减少设备，这项工作将开发一种工具来仅加速关键的通用原语并分析资源浪费，以设计减少的组件。第三，这项工作将设计更精简的微架构。在软件方面，这项工作将开发一种新颖的碳感知数据驱动资源管理框架，以实现每个硬件级别的碳高效设计。通过追求数据驱动技术，这项工作将凸显使用数据中心的价值。 ' 始终在线遥测这项跨学科研究跨越三个领域：计算机体系结构、软件系统和新应用范例，为可持续计算的跨学科工作开辟了新的机会。该奖项反映了 NSF 的法定使命，并通过评估被认为值得支持。利用基金会的智力优势和更广泛的影响审查标准。
