中文摘要
越来越多的计算趋势导致了一种新的分布式和高动态应用,其中空间感知起着核心作用。空间感知应用程序依赖于计算设备地理位置的绝对或相对信息,以支持新功能。虽然在移动和分布式计算中已经存在许多空间应用程序驱动程序,但对这些应用程序编程、表达其空间和时间约束以及支持优化层以在现实世界的高动态平台上有效实现的支持很少。本研究通过提供语言和系统层支持来表达和优化空间应用程序,从而解决了这些缺点。由于空间计算本质上是分布式的,因此密切关注程序内部和跨程序的资源共享和管理。该项目的SARANA系统架构包括(i)允许用户表达感兴趣的空间区域和所需结果质量的编程语言,(ii)可以优化程序以更有效地利用资源的编译器,以及(iii)动态安装并将程序迁移到资源可用性与其资源需求相匹配的物理节点上的运行时系统。资源成本模型渗透到SARANA的所有系统层,允许用户根据成本效益权衡来表达他们的资源需求和结果质量要求。运行时系统为资源和服务定价,以便就资源需求和可用性达成代理协议。SARANA的驾驶应用程序包括寻找被拐儿童的早期预警系统(Amber Alert)、地震监测系统和多用户游戏网络。
英文摘要
Increasingly, computing trends are leading to a new class of distributed and highly-dynamic applications in which spatial-awareness plays a central role. Spatially-aware applications rely on absolute or relative information about the geographic position of compute devices in order to support novel functionality. While many spatial application drivers already exist in mobile and distributed computing, very little support exists for programming these applications, expressing their spatial and temporal constraints, and supporting optimization layers for efficient implementation on real-world, highly-dynamic platforms. This research addresses these shortcomings by providing language- and system-layer support for expressing and optimizing spatial applications. Since spatial computing is inherently distributed, close attention is given to resource sharing and management within and across programs. The project's SARANA system architecture includes (i) a programming language that allows users to express the spatial region of interest and the quality of result required, (ii) a compiler that can optimize the program so it uses resources more efficiently, and (iii) a runtime system that dynamically installs and migrates the program onto physical nodes whose resource availability match its resource needs. A resource cost model permeates all the system layers of SARANA, permitting users to express their resource needs and quality of result requirements in terms of cost-benefit tradeoffs. . The runtime system prices resources and services, in order to broker agreements regarding resource needs and availability. SARANA's driving applications include an early warning system to find abducted children (Amber Alert), an earthquake monitoring system, and multi-user gaming networks.
