Abstract
Due to its high-level nature, parallel functional languages provide some advantages for the programmer. Unfortunately, the functional programming community has not paid much attention to some important practical problems, like debugging parallel programs. In this paper we introduce the first debugger that works with any parallel extension of the functional language Haskell, the de facto standard in the (lazy evaluation) functional programming community. The debugger is implemented as an independent library. Thus, it can be used with any Haskell compiler. Moreover, the debugger can be used to analyze how much speculative work has been done in any program.KeywordsHomomorphic ImageSpeculative WorkFunctional LanguageProcess AbstractionAlgorithmic SkeletonThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
