What is bounded blocking queue?
A blocking queue is defined as a queue which blocks the caller of the enqueue method if there’s no more capacity to add the new item being enqueued. Similarly, the queue blocks the dequeue caller if there are no items in the queue.
How the race condition occurs in producer consumer paradigm?
The consumer works analogously. With multiple producers sharing the same memory space for the item buffer, or multiple consumers sharing the same memory space, this solution contains a serious race condition that could result in two or more processes reading or writing into the same slot at the same time.
What is producer-consumer problem in multithreading?
In computing, the producer-consumer problem (also known as the bounded-buffer problem) is a classic example of a multi-process synchronization problem. The problem describes two processes, the producer and the consumer, which share a common, fixed-size buffer used as a queue.
Is producer a consumer problem?
In the producer-consumer problem, there is one Producer that is producing something and there is one Consumer that is consuming the products produced by the Producer. The producers and consumers share the same memory buffer that is of fixed-size. While the job of the Consumer is to consume the data from the buffer.
What happens when you try to consume from an empty queue?
If the consuming thread tries to take an object out of an empty queue, the consuming thread is blocked until a producing thread puts an object into the queue.
What is the producer-consumer problem in operating systems?
The Producer-Consumer problem is a classic problem this is used for multi-process synchronization i.e. synchronization between more than one processes. In the producer-consumer problem, there is one Producer that is producing something and there is one Consumer that is consuming the products produced by the Producer.
