In an asynchronous distributed system, independent processes run at varying speeds and may even crash; they communicate through unsynchronized primitives, like sending and receiving messages. To perform shared computation, processes need to coordinate their actions. This is theoretically modeled as solving a coordination task, where processes start with some inputs and have to output values satisfying certain conditions. A fundamental task is consensus, from which it is possible to solve any other coordination task. However, this task is not solvable in asynchronous environments in which process failure may occur. We study sub-consensus tasks, i.e., coordination tasks that are weaker than consensus. In particular, we focus on renaming which...
