Abstract: In this paper, we propose an output reproducible framework that executes parallel sequence comparison algorithms, computing the edit distance. The framework generates tables/graphics and linear regressions that can be used to predict the execution times. We also propose parallel OpenMP versions of serial algorithms (DP and UK) used to compute the edit distance. Our parallel DP is antidiagonal block-based, where the blocks that belong to the same set of antidiagonals are assigned to different threads, which compute them simultaneously. Due to data dependencies presented by UK, we opted to compute each antidiagonal in parallel. Our results with synthetic and real sequences show that the parallel UK version presents the best execution times in most cases. We also show that the linear regressions generated by our tool have errors below 10%, on average.
