Shared memory and message passing
WebbMessage passing also shares only immutable objects (the messages) between modules, whereas shared memory requires sharing mutable objects, which we have already seen can be a source of bugs. We’ll discuss in this reading how to implement message passing within a single process. Webb6.6.2 Message passing. Message-passing communication complements the shared memory model. As shown in Fig. 6.18, each communicating entity has its own message …
