A shared memory abstraction can be robustly emulated over an asynchronous message passing system where any process can fail by crashing and possibly recover (crash-recovery model), by having (a) the processes exchange messages to synchronize their read and ...
A concurrent object is an object that can be concurrently accessed by several processes. It has been shown by Maurice Herlihy that any concurrent object O defined by a sequential specification can be wait-free implemented from reliable atomic registers (sh ...

The vast majority of papers on distributed computing assume that processes are assigned unique identifiers before computation begins. But is this assumption necessary? What if processes do not have unique identifiers or do not wish to divulge them for reas ...

This paper determines necessary and sufficient conditions to implement wait-free and non-blocking contention managers in a shared memory system. The necessary conditions hold even when universal objects (like compare-and-swap) or random oracles are availab ...
Abstract. The vast majority of papers on distributed computing assume that processes are assigned unique identifiers before computation begins. But is this assumption necessary? What if processes do not have unique identifiers or do not wish to divulge the ...

Sequential consistency and causal consistency constitute two of the main consistency criteria used to define the semantics of accesses in the shared memory model. An execution is sequentially consistent if all processes can agree on a same legal sequential ...
A contention manager is a shared memory abstraction that boosts progress of obstruction-free algorithms. In this paper, we study the problem of the overhead of non-blocking and wait-free contention managers which use the minimal possible information about ...
It is considered good practice in concurrent computing to devise shared object implementations that ensure a minimal obstruction-free progress property and delegate the task of boosting liveness to independent generic oracles called contention managers. Th ...
