A failure detector is a distributed oracle that provides processes in a distributed system with hints about failures. The notion of a weakest failure detector captures the exact a...
This paper defines the basic notions of local and non-local tasks, and determines the minimum information about failures that is necessary to solve any non-local task in message-p...

Failure detector class Ωk has been defined in [18] as an extension to failure detector Ω, and an algorithm has been given in [16] to solve k-set agreement using Ωk in async...
This paper shows that, in an environment where we do not bound the number of faulty processes, the class P of Perfect failure detectors is the weakest (among realistic failure det...
