A Taxonomy of Distributed Debuggers Based on Execution Replay

This paper presents a taxonomy of parallel and distributed debuggers based on execution replay. Programming of distributed and parallel systems is a complex task. Amongst the many factors contributing to this complexity, the nondeterminacy of these systems is an important one. Execution replay is a technique developed to facilitate the debugging of nondeterministic programs. Execution replay has very broad applications and not every algorithm is applicable in every situation. This taxonomy provides a precise classi cation of replay debuggers using nine criteria. From this classi cation, it is easier to determine a debugger's scope of application, outline its strengths and weaknesses and compare it with others. This taxonomy is illustrated and validated using a collection of existing replay debuggers.
