Abstract

Abstract. We study the problem of monitoring concurrent program runs for atomicity violations. Unearthing fundamental results behind scheduling algorithms in database control, we build space-efficient monitoring algorithms for checking atomicity that use space polynomial in the number of active threads and entities, and independent of the length of run monitored. Second, by interpreting the monitoring algorithm as a finite automaton, we solve the model checking problem for atomicity of finite-state concurrent models. This remedies incorrect proofs published in the literature. Finally, we exhibit experimental evidence that our atomicity monitoring algorithm gives substantial time and space benefits on benchmark applications. 1
