EAGER: Mobile Multicore Computing

多核技术正在进入手机领域，在本项目中称为移动多核计算(MMC)。有了MMC，目前的手机不再是只有语音和/或视频电话功能的传统手机。这些小型设备集成了更多功能，如多媒体流媒体和移动P2P应用程序。MMC手机面临的巨大挑战是在性能和功率之间取得良好的平衡。不同于现有的面向硬件的方法，如时钟门控和功率门控以实现高性能和低功耗设计，该研究提出了面向软件的方法，如移动应用的功率感知并行化和功率感知任务调度来应对这一挑战。在这个为期两年的迫切项目中，PI正在寻求这一基础性能/功率权衡问题的答案。该方案提出了四个宏大的目标：1)考虑用户需求，为移动多核平台构建性能和功率权衡模型；2)在内存、时间和功耗受限的移动多核平台上并行处理移动应用；3)在内存、时间和功耗受限的多核平台上调度多任务；4)开发一个基于高性能和低功耗移动多核计算平台的原型系统。预计该项目得出的见解和成果将大规模惠及研究人员、从业者、用户和学生。

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.
