中文摘要
手持设备,如手机、平板电脑和可穿戴设备,在一个无处不在的世界中得到越来越多的采用。相应地,用户在这些设备上部署的媒体流、互动游戏、视频会议和社交网络等要求很高的交互式应用程序也出现了爆炸式增长。尽管这些设备中单个组件的能源效率有了巨大的提高,但硬件组件的零碎优化不足以满足这些应用程序的苛刻需求,这些应用程序同时以非常复杂的方式使用多个CPU内核、加速器、存储系统、系统外设和传感器。在运行此类应用程序时,系统资源之间缺乏协调导致资源利用率低和系统级能源效率差。这个项目提出了VIADUCT,而不是在这个问题上投入更多的硬件,它分配和协调系统级资源,以更节能的方式提高这些平台的并行性和资源利用率。认识到许多这些应用程序周期性地处理需要在软实时范围内通过几个硬件组件以流水线方式流动的数据帧,VIADUCT在应用程序中为这些帧的每个流创建一个虚拟通道。通道持有分配在所有硬件组件上的资源,通过运行时协调来确保无缝的帧移动,而不会在组件之间产生传统的低效率接口。细粒度调度和资源管理利用高级语义知识,以最节能的方式为每个流提供服务质量(QoS)。具体的研究贡献是硬件接口,机制和策略链硬件组件创建一个虚拟通道的流,架构内存系统作为一个有效的管道来维持这个流,并设计系统来维持几个并发流。该项目旨在为这些平台在更广泛的研究界提供一个全面的评估测试平台,同时也旨在让代表性不足的群体参与研究,并加强宾夕法尼亚州立大学的研究。相关主题的课程。
英文摘要
Handheld devices such as cell phones, tablets and wearables, are gainingrapid adoption in a ubiquitous world. Correspondingly, there is anexplosion of very demanding and interactive applications such as mediastreaming, interactive games, video conferencing and social networking,that users are deploying on such devices. Despite tremendousimprovements in the energy efficiencies of individual components foundin these devices, piece-meal optimizations of hardware components areinadequate to accommodate the demanding needs of these applications thatemploy multiple CPU cores, accelerators, memory systems, systemperipherals and sensors, concurrently in very sophisticated ways. Lackof coordination among system resources leads to low resource utilizationand poor system-level energy efficiencies when running suchapplications. Rather than throw more hardware at this problem, thisproject proposes VIADUCT, which allocates and orchestrates system-levelresources to boost parallelism and resource utilization for theseplatforms in a more energy-efficient fashion.Recognizing that many of these applications periodically process framesof data that need to flow in a pipelined manner through several hardwarecomponents within soft real-time bounds, VIADUCT creates a virtualchannel per flow of such frames in an application. The channel holdsresources allocated across all the hardware components, with runtimecoordination to ensure seamless frame movements without the conventionalinterface inefficiencies across the components. Fine-grain schedulingand resource management leverages knowledge of high level semantics toprovide Quality-of-Service (QoS) for each flow in the mostenergy-efficient fashion. The specific research contributions are inhardware interfaces, mechanisms and policies to chain the hardwarecomponents for creating a virtual channel for a flow, architecting thememory system as an efficient conduit to sustain this flow, anddesigning the system to sustain several concurrent flows. The projectaims to provide a holistic evaluation testbed for such platforms amongstthe broader research community, and also aims to involveunder-represented groups in the research and enhance Penn State?scurriculum in related topics.
