★ Producer-Consumer modelFirst of all, we analyze the producer and consumer models: producers and consumers are indispensable in the model of 2 roles, of course, the model must need a place to save data, can be produced by producers of data storage. At the same time, the model must meet the producers to produce data, consumers can use, that is, consumers must be located in the

3. Producer-Consumer RealizationProducer Consumer Issues (English:producer-consumer problem), also known as limited buffering problems (English:bounded-buffer problem), is a classic case of a multithreaded synchronization problem. The problem describes two threads that share fixed-size buffers-the so-called "producer" and "consumer"-problems that can occur when they actually
If there is no such object as a generator, how can this simple "producer-consumer" model be implemented?Import timeDef producer ():Pro_list = []For I in range (10000):Print "Bun%s made ing"% (i)Time.sleep (0.5)Pro_list.append ("Bun%s"%i)Return pro_listDEF consumer (pro_list):For Index,stuffed_bun in Enumerate (pro_list):Print "%s personal, ate the first%s buns"% (Index,stuffed_bun)Pro_list =
Spring Festival back to the hometown, and experienced a water table, due to more tables, resulting in slow serving, so in the waiting room, summed up a few characteristics of the process of the vegetables:1. There are many cooking stoves, many cooking stoves are at the same time cooking out.2. Cooked dishes, there will be a person with a tray end out, each end of the dish (is the same dish) the number of different.3. Because the end dish may not meet all the table number, so, the end dish people
Multi-producer Multi-consumer is a classic case in Java, implemented by the wait-wake mechanism, the code is as follows: Public classProducerconsumer { Public Static voidMain (string[] args) {Resource res=NewResource (); Producer Pro1=NewProducer (RES); Producer Pro2=NewProducer (RES); Consumer Con1=NewConsumer (RES); Consumer Con2=NewConsumer (RES); Thread T1=

Producer Consumer IssuesThe problem description is: There is a group of producer processes in the production of products, this product is provided to consumers to consume. To enable producer and consumer processes to execute concurrently, set up a pool of n buffers between them, the producer process can put the product
In multithreaded development, one of the most classic models is the producer consumer model, they have a buffer, the buffer has the maximum limit, when the buffer is full, the producer is unable to put the product into the buffer, of course, when the buffer is empty, the consumer can not take out the product, whichRelated to the conditional judgment in multi-threading, Java in order to implement these funct
IdeasProducers and consumers (mutual exclusion and synchronization). The resource is simulated with a queue (to be locked, only one thread can operate the queue at a time). M a producer. Get the lock, and product dissatisfaction, can be produced. When the product is full, wait for the consumer to wake up. When the product from empty to not empty, inform the consumer.n a consumer. Get the lock, and have the product, in order to consume. When the produc
Excerpt from Python core programmingIn this example, the producer-consumer model: the producer of a commodity or service produces a commodity and then puts it into a queue-like data structure. The time in the production of goods is uncertain, and the time for consumers to consume goods is also uncertain.Use the queue module (called queue in the python2.x version) to provide a mechanism for inter-thread comm
One.In version 1.5, the original form was changed, but the functionality did not change, so what was the reason for doing so?Previously, we had a lock with only a set of monitors that monitored both the producer and the consumer. This set of monitors can wait for both producers and consumers, as well as to awaken producers and consumers alike. or notify, it can also wake up one of the threads, and one of them is not sure who it is, it could be the par
Here is a producer consumer question to introduce the use of condition_variable. When shared data between threads changes, it is possible to notify other threads through condition_variable. Consumers wait until the producer notifies them that the state has changed, condition_variable is used as follows:• When a lock is held, the thread calls the waitwait unlocks the held mutex (mutex), blocks this thread, a
Producer consumer problem is a typical process synchronization mutex problem in operating system, (English: Producer-consumer problem), also called limited buffer problem (English: Bounded-buffer problem), it is a classic case of multithreading synchronization problem.

1. Basic knowledge1). There are 3 types of relationships in the producer consumption model:A. There is mutual exclusion between producer and manufacturer;B. There is mutual exclusion between consumers and consumers;C. Between the producer and the consumer is synchronous and mutually exclusive;2). Producer and consumer
