Over the past 45 years, computer scientists and engineers have transformed plentiful transistors into computational capability. At present, energy costs jeopardize further capability scaling, especially in datacenters. Given constrained datacenter power budgets, which are already at megawatt scales, this project is developing new paradigms to design and deploy heterogeneous datacenter architectures to improve energy efficiency by an order of magnitude. Heterogeneity specializes hardware for particular applications and deploys a mix of hardware for a mix of application needs. Specialization improves efficiency as overheads from supporting general, arbitrary computation are reduced. To realize heterogeneous efficiency, this project is rethinking design and deployment. Rethinking design to reduce specialization costs, this project is parameterizing hardware designs to facilitate their re-use, applying statistical inference to explore design spaces, and clustering applications that have similar hardware needs to increase each design?s market volume. Rethinking deployment to reduce performance risk, this project is developing multi-agent systems that transparently manage and allocate heterogeneous resources to meet performance targets. This project has the potential to impact the composition and management of datacenters that underpin cloud computing. As access to cloud computing is democratized, diverse users will seek computation. And this project is architecting energy-efficient infrastructure to provide that computation. The design and deployment of heterogeneous architectures requires a holistic view of computer systems. The project is integrating research with curricular development, broadening students? views of processor, memory, network, and storage. The project is engaging all students at all levels of education and from all backgrounds, preparing future generations for computer engineering and research.

在过去的 45 年里，计算机科学家和工程师将大量的晶体管转化为计算能力。 目前，能源成本危及进一步的能力扩展，尤其是在数据中心。 鉴于数据中心功率预算已经达到兆瓦级，该项目正在开发新的范例来设计和部署异构数据中心架构，以将能源效率提高一个数量级。 异构性专门针对特定应用程序的硬件，并针对各种应用程序需求部署混合硬件。 专业化提高了效率，因为支持通用、任意计算的开销减少了。为了实现异构效率，该项目正在重新思考设计和部署。 该项目重新思考设计以降低专业化成本，对硬件设计进行参数化以促进其重复使用，应用统计推断来探索设计空间，并对具有类似硬件需求的应用程序进行聚类以增加每个设计的市场容量。 该项目正在重新考虑部署以降低性能风险，正在开发多代理系统，该系统可以透明地管理和分配异构资源以满足性能目标。 该项目有可能影响支撑云计算的数据中心的组成和管理。 随着云计算的使用变得民主化，不同的用户将寻求计算。 该项目正在构建节能基础设施来提供这种计算。 异构架构的设计和部署需要对计算机系统有一个整体的看法。 该项目将研究与课程开发相结合，拓宽了学生的视野。处理器、内存、网络和存储的视图。 该项目吸引了所有教育层次和背景的所有学生，为子孙后代进行计算机工程和研究做好准备。
