The parascope editor: an interactive parallel programming tool

Abstract

The ParaScope project is building an integrated collection of tools to help scientific programmers develop correct and efficient parallel programs. The centerpiece of this collection is the ParaScope Editor, an intelligent interactive editor for parallel FORTRAN programs. The ParaScope Editor displays data dependencies, which correspond to potential data races among the iterations of a parallel loop, to assist the user in determining the correctness of a proposed parallelization. In addition, it uses dependencies to support a variety of program transformations selectable by the programmer.
