CAREER: EOC: An Energy-Aware Optimizing Compiler Framework

直到最近，性能一直是硬件和软件设计中最重要的问题。 然而，随着电池供电的嵌入式和便携式设备的激增以及通用处理器的时钟频率的不断增加，有效能量优化的问题对于各种各样的架构已经变得非常重要。 该项目的目标是设计和实现一个能量感知优化编译器框架，该框架将以高级语言编写的源代码、能量和性能约束、架构描述和技术相关参数作为输入，并生成能量/性能优化的可执行文件和能耗估计作为输出。 一些关键的贡献包括：（i）高层次的能源模型，可以使用的编译器，（ii）一个模拟器的基础设施，以验证编译器的输出，（iii）新的，面向能源的编译器优化，以及（iv）调查必要的操作系统和架构支持编译器，操作系统和架构之间的有效合作，以解决日益增长的能源问题在一个统一的方式。 提出的能源/性能感知的方法代表了一个根本性的转变，从纯粹的性能为导向的策略，到目前为止，在优化编译器，并将开辟新的途径，在计算的世界，越来越多的能源意识。

Until recently, performance has been the single most important issue in the design of hardware and software. However, with the proliferation of battery-powered embedded and portable devices and the ever-increasing clock frequencies of general-purpose processors, the problem of effective energy optimization has become very important for a wide variety of architectures. The goal of this project is to design and implement an energy-aware optimizing compiler framework that take as input a source code written in a high-level language, energy and performance constraints, architectural description and technology related parameters, and generates as output an energy/performance optimized executable and an estimation of energy consumption. Some key contributions include (i) high-level energy models that can be used by a compiler, (ii) a simulator infrastructure to validate compiler output, (iii) new, energy-oriented compiler optimizations, and (iv) investigating the necessary os and architectural support for effective cooperation between the compiler, os, and architecture so as to address the growing energy problem in a unified manner. The proposed energy/performance-aware approach represents a radical shift from pure performance-oriented strategies used so far in optimizing compilers, and will open new avenues of research in computing in a world that is increasingly becoming more energy-conscious.
