MPP环境下的数据分割和数据的局部化

Data Division in Environment of MPP & the Locality of Data

针对在ＭＰＰ体系结构的基础上进行并行化编译的若干实例的研究，对在分离的存储器的结构上进行数据划分和相应数据（特别是数组）的局部化技术进行了初步的讨论和分析，提出了自己的看法和一些简单的技术和方法，这主要包括：（１）避免数据重组的数据划分；（２）数据的冗余划分；（３）多种迭代对数据划分的一致性要求；（４）数组的局部化算法及主要类型。

In this article,through the research of the parallelizing compilation of some instances in the fundamention of MPP computer constuction,we make basic discussion and analysis to the data divison in the structure of divided stotages and the locality of relative data(especially arrays),and we give our opinions and some simple technique and methods,majorly include; (l) data division without data reorganization; (2) data redundant division; (3) insistent request of data division in varities of iterations; (4) locality algorithm of array and the major type
