Many critical online services are turning to cloud infrastructure to meet scalability demands. In order to sustain cloud computing growth, it is necessary to scale the computational capacity, and improve the energy efficiency, of data centers. Modern data centers increasingly integrate accelerators, such as Graphical Processing Units (GPUs), with traditional CPUs to provide unprecedented parallelism and order-of-magnitude improvement to computational throughput. In order to manage software workloads and hardware resources at cloud-scale, data centers are increasingly being virtualized to provide ease of software and hardware management. However, existing energy efficiency techniques are not well-suited for virtualization technology and heterogeneous hardware. This project provides fundamental insights and solutions towards achieving energy-efficient computing for emerging virtualized heterogeneous data centers. This project has wide-reaching benefits for the computational engines behind many workloads of national interest, such as weather forecasting and machine learning. Results of this research are being integrated into the existing undergraduate and graduate courses.The research consists of three main thrusts: 1) development of heterogeneous benchmarks to evaluate server energy profile and metrics to quantify heterogeneous server energy proportionality in order to investigate the implications of virtualization and heterogeneous architectures, 2) development of software support for container live migration and performance-aware migration strategies to minimize live migration overhead, 3) development of management techniques to maximize energy proportionality of heterogeneous CPU and multi-accelerator systems, such as dynamic load balancing and automatic runtime task migration.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.

许多关键的在线服务正在转向云基础架构以满足可扩展性需求。为了维持云计算的增长，有必要扩展数据中心的计算能力并提高能源效率。现代数据中心越来越多地将加速器（例如图形处理单元（GPU））与传统的CPU相结合，以提供前所未有的并行性和数量的改进，以改善计算吞吐量。为了管理云规模的软件工作负载和硬件资源，数据中心越来越虚拟化以提供软件和硬件管理的易用性。但是，现有的能源效率技术不适合虚拟化技术和异质硬件。该项目为新兴虚拟化异质数据中心实现节能计算提供了基本的见解和解决方案。该项目对许多国家兴趣工作的计算机具有广泛的好处，例如天气预报和机器学习。 Results of this research are being integrated into the existing undergraduate and graduate courses.The research consists of three main thrusts: 1) development of heterogeneous benchmarks to evaluate server energy profile and metrics to quantify heterogeneous server energy proportionality in order to investigate the implications of virtualization and heterogeneous architectures, 2) development of software support for container live migration and performance-aware migration strategies to minimize live migration开销，3）开发管理技术，以最大化异质性CPU和多加速器系统的能量比例，例如动态负载平衡和自动运行时任务迁移。该奖项反映了NSF的法定任务，并通过使用该基金会的知识分子功能和广泛的影响来评估Criteria criteria criteria criteria criteria。
