Synchronization

Synchronization. Tanenbaum Chapter 5. Synchronization. Multiple processes sometimes need to agree on order of a sequence of events. This requires some synchronization, which is more elaborate in distributed systems. Synchronization may be based on time (absolute or relative), leader election

Centralized mutual exclusion

Centralized mutual exclusion. Problem : What if the coordinator fails? Solution : Elect a new one. Leader Election : Problem Statement. Given is a set of n processes, 1 .. n. Each process j has variables : l.j : true iff j is a leader up.j : true iff j has not failed
