数据并行的性能分析

POTENTIAL IN DATA PARALLELISM

计算机是一种工具．作为工具，其应用的成功与否具有重要的意义．本文从应用的角度分析了数据并行处理方式下并行处理的性能．首先，本文建立了一个性能分析模型，之后，基于此模型，对影响并行处理性能的各因素进行了详细地分析．本文的分析结果对于并行算法的设计者和并行计算机系统的设计者均具有指导意义．

This paper, from application viewpoint, analyzes the potential in data parallelism. First, they propose a speedup analysis model. Then, based on the model a comprehensive analysis on speedup is presented. These analytical results could be used to guide the design of parallel processing systems as well as parallel algorithms.
