Analysis and transformation in the ParaScope editor
Ken Kennedy, Kathryn S. McKinley, Chau‐Wen Tseng · 1991
The ParaScope Editor is a new kind of interactive parallel programming tool for developing scientific Fortran programs. It assists the knowledgeable user by displaying the results of sophisticated program analyses and by providing editing and a set of powerful interactive transformations. After an edit or parallelism-enhancing transformation, the ParaScope Editor incrementally updates both the analyses and source quickly. This paper describes the underlying implementation of the ParaScope Editor, paying particular attention to the analysis and representation of dependence information and its reconstruction after changes to the program. 1 Introduction The ParaScope Editor is a tool designed to help skilled users interactively transform a sequential Fortran 77 program into a parallel program with explicit parallel constructs, such as those in PCF Fortran [40]. In a language like PCF Fortran, the principal mechanism for the introduction of parallelism is the parallel loop, which specif...
