Titre

(Almost) All Atomic Objects are Equal in a Distributed System

Résumé

This talk revisits some of the fundamental results in distributed computing by stating that the knowledge about failures needed to implement (almost) all atomic objects in a distributed system is the same. In particular, objects like queue, test-and-set, fetch-and-add, known to have a weak synchronization power in a multiprocessor system, are in a precise sense equivalent in a message passing distributed system to objects like compare-and-swap, known to have a strong synchronoization power.

Joint work with C. Delporte and H. Fauconnier from paris VII

La conférence sera donnée en français (avec un accent marocain) si les auditeurs sont tous francophones. Sinon, elle sera donnée en anglais (avec un accent français).
