An increasing amount of computation is moving into the Cloud and large-scale data centers. Hosted web-applications, such as social networks, hosted email, and photo sharing, are all examples of applications, which have moved into the Cloud. In order to control costs and save energy, maximizing the computational efficiency of datacenter computers is of paramount importance. This research project investigates computational efficiency in datacenter processors by looking for commonality between all of the applications that are executing in the Cloud. This project explores how to change a microprocessor core to save energy by exploiting the commonality available between applications in the Cloud. In addition, this project utilizes an integrated education plan that will disseminate information about computer architecture inside of the University, across the New York region, and across the world through the use of a Massively Open Online Course (MOOC). Accelerating data center and big data applications can have large societal impact by helping humans understand data that has been collected, thus enabling the understanding of social trends and public health challenges. The success of the research project will create more efficient data centers that will enable humanity to answer societal big data questions and have richer Internet experiences.This project investigates how to create computer architectures that can exploit similarity between programs executing on different cores across the data center. A software system identifies likely candidates that exhibit commonality. Once likely commonality has been identified, micro-architectural information is sent between different cores or within a single core to enable the execution of one program to reduce the energy needed to execute a second similar program. This project investigates what is the best micro-architectural information to share between cores executing common programs and how it is best to send that information between cores. In particular, this project investigates customizing on-chip networks specialized for sending commonality information and how to modify a manycore processor to harvest common micro-architectural information.

越来越多的计算量正在转移到云和大型数据中心。 托管网络应用程序，例如社交网络、托管电子邮件和照片共享，都是已转移到云中的应用程序的示例。 为了控制成本和节省能源，最大限度地提高数据中心计算机的计算效率至关重要。 该研究项目通过寻找在云中执行的所有应用程序之间的共性来研究数据中心处理器的计算效率。 该项目探讨了如何通过利用云中应用程序之间的通用性来改变微处理器核心以节省能源。 此外，该项目采用综合教育计划，通过大规模开放在线课程（MOOC）在大学内部、整个纽约地区以及全世界传播有关计算机体系结构的信息。 加速数据中心和大数据应用可以帮助人类理解已收集的数据，从而了解社会趋势和公共卫生挑战，从而产生巨大的社会影响。该研究项目的成功将创建更高效​​的数据中心，使人类能够回答社会大数据问题并拥有更丰富的互联网体验。该项目研究如何创建可以利用整个数据中心不同内核上执行的程序之间的相似性的计算机架构。 软件系统可以识别具有共性的可能候选者。 一旦识别出可能的共性，就会在不同内核之间或在单个内核内发送微架构信息，以便能够执行一个程序，从而减少执行第二个类似程序所需的能量。 该项目研究了在执行通用程序的核心之间共享的最佳微架构信息是什么，以及如何最好地在核心之间发送该信息。 特别是，该项目研究了专门用于发送通用信息的定制片上网络以及如何修改众核处理器以获取通用微架构信息。
