In this paper we consider the k-set agreement problem in distributed round-based systems where processes communicate by message passing. We capture the synchrony and reliability o...
Abstract. To cope with the impossibility of solving agreement problems in asynchronous systems made up of n processes and prone to t process crashes, system designers tailor their ...
: Weprove tight bounds on the time needed to solve k-set agreement, a natural generalization of consensus. We analyze this problem in a synchronous, message-passing model where pro...

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...
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...
