Congratulation to Armando CASTAÑEDA*, Sergio RAJSBAUM* and Michel RAYNAL† for their paper Unifying Concurrent Objects and Distributed Tasks: Interval-Linearizability that has been accepted in the Journal of the ACM (JACM).
- The first is a generalization of the of the concept of Linearizability to concurrent objects that have no sequential specification.
- The second is on the equivalence between the notion of an “object” and the notion of “task”. The notion of a task to distributed computing generalizes the classical notion of a (mathematical) function used in sequential or parallel computing.
These two points are new and paves the way to better understand the deep nature of concurrent distributed computing.
