A producer is a concurrent component or thread that creates values and enters them into a shared queue. In a producer–consumer design, it coordinates with consumers through a bounded queue, mutex, and condition variables. section 16.3.2
Two producers and three consumers
A shared queue with capacity eight receives five values from each of two producer threads. Three consumers remove values concurrently; output shows insertion and removal order as scheduling varies.
