We determine what information about failures is necessary and sufficient to solve Consensus in asynchronous distributed systems subject to crash failures. In Chandra and Toueg [199...

: This paper is on failure detectors to solve the consensus problem in asynchronous systems made up of anonymous processes prone to crash and connected by asynchronous reliable cha...
The concept of unreliable failure detector was introduced by Chandra and Toueg [2] as a mechanism that provides information about process failures. Depending on the properties the...
The power of an object type T can be measured as the maximum number n of processes that can solve consensus using only objects of T and registers. This number, denoted cons(T), is ...
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...
