In this paper we discuss and compare three different causality inconsistency tracking mechanisms in support of preemptive rollback in optimistic parallel simulation on myrinet clusters. These mechanisms exhibit different communication/ processing overhead and also different effectiveness in revealing causality inconsistency of the currently executed simulation event. By the results of an empirical study on a classical simulation benchmark we have found some trade-offs between these mechanisms, pointing out indications of application contexts for which each mechanism is expected to be well tailored.
