![]() Let’s look at the code for the Producer and Consumer processes. Using the signal() and wait() operations on these semaphores, we can arrive at a solution. semaphore mutex: Used for mutual exclusion so that only one process can access the shared buffer at a time.It is initially set to buffer_size as the whole buffer is empty at the beginning. semaphore Empty: Tracks the empty space in the buffer.If you think of YouTube, whenever a user adds a video, hes acting in a Producer role, creating. It is initialized with a value of 0 0 0 as the buffer will have 0 0 0 filled spaces at the beginning Producer: Someone who creates supply or responds to demand. semaphore Full: Tracks the space filled by the Producer process.The solution to the Producer-Consumer problem involves three semaphore variables. The Consumer process must not consume an item if the shared buffer is empty.Īccess to the shared buffer must be mutually exclusive this means that at any given instance, only one process should be able to access the shared buffer and make changes to it. The Producer process must not produce an item if the shared buffer is full. ![]() The tricky partĬertain conditions must be met by the Producer and the Consumer processes to have consistent data synchronization: The Consumer process takes items out of the shared buffer and “consumes” them. The Producer process creates an item and adds it to the shared buffer. The problem is defined as follows: there is a fixed-size buffer and a Producer process, and a Consumer process. The Producer-Consumer problem is a classic synchronization problem in operating systems.
