Zusammenfassung This paper contributes to the analysis of the Non-Blocking Atomic Commit (NBAC) problem in an asynchronous model with failure detectors. In particular, we address the question of the weakest failure detector to solve NBAC in this model. We define the set A of timeless failure detectors which excludes failure detectors that provide information about global time but includes most known meaningful failure detectors such as ◊S, ◊P and P [2]. We show that, within A, the weakest failure detector for NBAC is ?P+◊S. As a corollary of our results, we state out the relationship between NBAC and another famous agreement problem in distributed computing – Consensus.
