EAGER: Mobile Multicore Computing

多核技术正在进入移动电话领域，本项目称之为移动多核计算（MMC）。有了MMC，现在的手机不再是只有语音和/或视频通话功能的传统手机。更多的功能，如多媒体流媒体和移动P2P应用程序，被集成到这些小型设备中。MMC手机的最大挑战是在性能和功率之间进行良好的权衡。与现有针对高性能低功耗设计的时钟门控和功率门控等面向硬件的方法不同，本研究提出了面向软件的方法，如移动应用程序的功率感知并行化和功率感知任务调度来应对这一挑战。在这个为期2年的EAGER项目中，PI正在寻找这个基本性能/功率权衡问题的答案。该提案提出了四个雄心勃勃的目标：1)为考虑用户需求的移动多核平台构建性能和功耗权衡模型；2)在内存、时间和功耗限制下，并行化移动多核平台上的移动应用；3)在内存、时间和功率限制的多核平台上调度多任务；4)开发基于移动多核计算平台的高性能低功耗移动系统原型。预计从这个项目中得出的见解和结果将在很大程度上使研究人员、从业者、用户和学生受益。

Multicore technology is entering the mobile phone domain, and it is termed mobile multicore computing (MMC) in this project. With MMC, the current mobile phones are no longer the traditional mobile phones with only voice and/or video phone functionalities. More features, such as multimedia streaming and mobile P2P applications, are integrated into these small devices. The grand challenge in MMC mobile phones is making a good tradeoff between performance and power. Different from existing hardware-oriented approaches, such as clock gating and power gating for high performance and low power design, this research proposes software-oriented approaches such as power-aware parallelization of mobile applications and power-aware task scheduling to meet this challenge.In this 2-year EAGER project, the PI is seeking answers to this foundational performance/power tradeoff problem. The prposal sets forth four ambitious objectives to do so: 1) To build a performance and power tradeoff model for mobile multicore platforms considering user requirements; 2) To parallelize mobile applications for mobile multicore platforms with memory, timing, and power constraints; 3) To schedule multitasks for multicore platforms with memory, timing, and power constraints; and 4) To develop a prototype mobile system based on mobile multicore computing platforms with high performance and low power consumption. It is expected that the insights and results drawn from this project will benefit researchers, practitioners, users, and students on a large scale.
