一个面向对象的应用生成器OO—HLL

ＯＯ－ＨＬＬ是一个ＯＲＡＣＬＥ Ｐｒｏ＊Ｃ应用生成器,它以面向对象和第四代语言面向问题的非过程方式定义用户需求,生成可嵌入ＳＱＬ语句到Ｃ程序中的Ｐｒｏ＊Ｃ程序,然后通过Ｐｒｏ＊Ｃ预编译程序和Ｍｉｃｒｏｓｏｆｔ Ｃ编译器将其翻译为可执行的目标代码。本文介绍了ＯＯ－ＨＬＬ的基本思想,给出了ＯＯ－ＨＬＬ语言主要语法成分的形式定义,讨论了它的代码生成技术。     

Shared Variable Oriented Parallel Precompiler for SPMD Model

For the moment,commercial parallel computer systems with distributed memory architecture are usually provided with parallel FORTRAN or parallel C compliers,which are just traditional sequential FORTRAN or C compilers expanded with communication statements.Programmers suffer from writing parallel programs with communication statements. The Shared Variable Oriented Parallel Precompiler (SVOPP) proposed in this paper can automatically generate appropriate communication statements based on shared variables for SPMD(Single Program Multiple Data) computation model and greatly ease the parallel programming with high communication efficiency.The core function of parallel C precompiler has been successfully verified on a transputer-based parallel computer.Its prominent performance shows that SVOPP is probably a break-through in parallel programming technique.
