Design of Synchronization Algorithms


In these notes we discuss the design of concurrent programs that consist of a set of communicating sequential processes. The processes communicate via shared variables and synchronize via semaphores. We present an axiomatic definition of semaphores, and prove properties about them. The split binary semaphore is introduced and it is shown how it can be used in constructing the synchronization part of concurrent processes in order to maintain a given synchronization condition.
