11 )发展了国内第一个高效并行海洋环流模式:深入研究了中国科学院大气物理所第三代海洋环流模式，分析了其串行计算特点和并行可扩展性，指出了其计算方法上存在的对并行计算的某些限制，对该模式组织了有效并行计算，并成功应用了包括多重叠边界在内的若干并行优化方法，在国产小型mpp系统和sgioriginzoo 。 - Nowadays , the most popular parallel computer architectures in the world are smp , mpp , cow and smp cluster , etc . smp cluster , which combines the characteristics of both shared memory and distributed memory architectures , is not only powerful in computing capabilities but also excellent in scalabilities
目前国内外流行的并行计算机体系结构主要有smp 、 mpp 、 cow和smp集群等,其中smp集群体系结构结合了共享存储和分布式存储两种体系结构的特点,同时兼顾了计算性能和可扩展性两个方面。 - For the process of simulation , the databases are supposed to be provided with two sides : real - time access for the distributed memory data and intelligence simulation technology . because each site in this simulation database emulates the different position and function structure character , and comes down to multi - platform , multi - type data , the great amount of system parameters , models , model structure parameters and rules in simulation must be managed by distributed database for administration , rapid information query and dynamic storage modification
由于该仿真系统的每一个仿真节点分别模拟了分布在不同位置、不同功能结构特征的仿真对象，而且，涉及到多平台、不同形式和种类的数据，因此仿真过程中大量的系统参数、模型、模型结构参数和规则，都必须使用分布式数据库技术来管理、进行高速的数据检索和动态存储修改，来支持仿真环境的动态维护与仿真环境之间的相互作用。 - 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。
