Abstract:Dataflow analysis-based dynamic parallel monitoring (DADPM) is a recent approach for identifying bugs in parallel software as it executes, based on the key insight of explicitly modeling a sliding window of uncertainty across parallel threads. While this makes the approach practical and scalable, it also introduces the possibility of false positives in the analysis. In this paper, we improve upon the DADPM framework through two observations. First, by explicitly tracking new "uncertain" states in the metadata … Show more
