The goal of the project is to create a framework to enable the design of reconfigurable multiprocessors . This project addresses and develops solutions for the problems of: (a) dynamic identification and prediction of program phases in parallel codes, and (b) their application to reconfigurable parallel computing. The proposal will: (1) Study the design and implementation of multiprocessor phase identifiers and their integration with phase predictors, and specifically will analyze the shortcomings of current uniprocessor approaches in the context of multiprocessor systems, and propose alternative/supplementary means of gathering and utilizing phase information. (2) Develop novel metrics suitable for quality assessment of multiprocessor phase identifiers and predictors overcoming the shortcomings of traditional uniprocessor approaches. (3) Aggregation and integration of COTS phase-adaptive systems (e.g., adaptive chip multiprocessors). (4) General exploration of phase-adaptive multiprocessor systems.

该项目的目标是创建一个框架来实现可重构多处理器的设计。该项目解决并开发了以下问题的解决方案：(a)并行代码中程序阶段的动态识别和预测，以及(b)它们在可重构并行计算中的应用。(1)研究多处理器相位标识符的设计与实现及其与相位预测器的集成，具体分析当前单处理器方法在多处理器系统背景下的不足，提出收集和利用相位信息的替代/补充方法。(2)克服传统单处理器方法的缺点，开发适合于多处理器相位标识符和预测器质量评估的新度量。(3) COTS相位自适应系统的聚合与集成（如自适应芯片多处理器）。(4)相位自适应多处理器系统的一般探索。
