distributed memory system meaning in English

分散记忆系统

We analysed the traditional automatic parallelization technology , including dependency analysis theory , program transformation technology , parallel scheme and the optimization of related synchronization and communication etc , which are the theoretical basis of the whole article . cfd computing features , especially the features of explicit difference computing , have also been further ananlysed . we also summarized drawbacks of traditional automatic parallelization technology used in cfd : small parallel granularity , difficulty in attaining global identical data partition , and difficulty in attaining high parallel efficiency on distributed memory system
本文讨论、分析、总结了通用的自动并行化技术：相关性分析理论、程序变换技术、并行模式以及同步通信与优化问题等等，它们是本文研究工作的理论基础；针对研究对象，深入分析了cfd计算的特点，特别是显式差分计算的特点；并归纳出传统的自动并行化技术在cfd应用中存在的问题：并行粒度小、难以获得全局统一的数据划分方式，对于分布存储结构的并行机难以获得高效率。
