随着万维网(WWW)的广泛使用,程序越来越多地在虚拟机上运行,虚拟机被动态编译以实现高性能。然而,动态编译本身的能量效率和动态编译器在运行时可以有效地执行的面向能量的优化仍然在很大程度上未被探索。该项目从能耗的角度研究动态编译过程,并正在开发各种新颖的优化策略,从纯基于软件的动态转换到编译器指导的动态能源管理,运行时自适应和架构定制。 这项工作旨在系统地和大幅度地降低虚拟机上运行的移动的应用程序的能耗,而不显着影响performance.The成功的这项研究预计将加速Java编程语言的应用到更广泛的各种能源受限的嵌入式系统,如移动的电话和PDA。随着能源效率的提高和电池寿命的延长,可以为移动的设备开发具有丰富功能的新应用。 本科生和研究生参与了这项研究的各个方面。作为该项目的一项成果,正在研究生和本科生一级提供新的和加强的课程。开发的软件包和课程材料通过研究网站公开提供,供其他研究人员或机构使用。
英文摘要
With the widespread use of the World Wide Web (WWW), programs are increasingly run on virtual machines, which are compiled dynamically to achieve high performance. However, the energy efficiency of the dynamic compilation itself and energy-oriented optimizations that can be efficiently performed by the dynamic compiler at runtime are still largely unexplored. This project studies the dynamic compilation process from the energy consumption perspective and is developing a variety of novel optimization strategies, ranging from pure software-based dynamic transformations to compiler-directed dynamic energy management, runtime adaptation and architectural customization. This effort seeks to systematically and substantially reduce the energy consumption of mobile applications running on virtual machines, without significant impact on performance.The success of this research is expected to accelerate the application of Java programming language to a wider variety of energy-constrained embedded systems, such as mobile phones and PDAs. With improved energy efficiency and prolonged battery lifetime, new applications with rich functionality can be developed for mobile devices. Undergraduate and graduate students are involved in all aspects of this research. New and enhanced courses at the graduate and undergraduate level are being offered as an outcome of this project. The developed software packages and course material are made publicly available through the research website, for use by other researchers or institutions.
