PORT：并行优化重构工具集

PORT: A SET OF PARALLELIZING OPTIMIZING RESTRUCTURING TOOLS

ＰＯＲＴ是以ＦＯＲＴＲＡＮ７７源程序为对象的并行优化重构工具集．它以自动并行重构程序为主体，辅以一组优化、静态分析、动态分析和程序执行过程可视化工具．通过良好的用户界面和统一的内部数据结构将它们集成为一个整体．本文介绍ＰＯＲＴ系统的特点、结构和若干关键技术．

PORT is a set of parallelizing optimizing restructuring tools. Its principal part is a restructurer that translates FORTRAN 77 programs to extended FORTRAN programs with parallel directives and assertions. PORT system also provides a collection of efficient and powerful graphical tools for static analysis, dynamic analysis, program debugging and computing process visualization by a friendly graphical user interface. They are integrated with consistent internal data structures. This paper presents the organization of PORT system. Some specific topics are: front end of PORT, solve call relationship, interprocedural analysis, global constant propagation, induction variable substitution, data dependence analysis,alias processing, De loop translations and parallel code generation.
