“Since the early work of E.W. Dijkstra (1965), who introduced the mutual exclusion problem, the concept of a process, the semaphore object, the notion of a weakest precondition, and guarded commands (among many other contributions), synchronization is no longer a catalog of tricks but a domain of computing science with its own concepts, mechanisms, and techniques whose results can be applied in many domains. This means that process synchronization has to be a major topic of any computer science curriculum.”
