Incremental dependence analysis for interactive parallelization
Pages 330 - 341
Abstract
Incrementally updating dependence information during interactive parallelization is a difficult proposition. We have developed a tool (PAT) that maintains dependence information during incremental transformations to a Fortran program, including loop parallelization, code replication, alignment and shifting, as well as insertion and deletion of code including parallel primitives. Our analysis is based on a variation on the standard approach to dependence graph generation, with program wide and local information separated in a sequential and a parallel dependence graph.
