Random Fact: Did you know that C++ was originally called āC with Classesā? Talk about an evolution in nomenclature!
Program Code ā C++ Concurrency Models in Real-Time System Design
#include <iostream>
#include <thread>
#include <vector>
#include <mutex>
#include <condition_variable>
#include <queue>
#include <chrono>
using namespace std;
using namespace std::chrono;
// A lambda function that simulates a long-running task.
auto simulateWork = [](int duration) {
this_thread::sleep_for(milliseconds(duration));
};
// Thread-safe queue class to handle concurrent access.
template<typename T>
class ThreadSafeQueue {
private:
queue<T> dataQueue;
mutable mutex mtx;
condition_variable dataCond;
public:
ThreadSafeQueue() {}
void push(T new_value) {
lock_guard<mutex> lk(mtx);
dataQueue.push(new_value);
dataCond.notify_one();
}
void wait_and_pop(T& value) {
unique_lock<mutex> lk(mtx);
dataCond.wait(lk, [this]{return !dataQueue.empty();});
value = dataQueue.front();
dataQueue.pop();
}
bool try_pop(T& value) {
lock_guard<mutex> lk(mtx);
if(dataQueue.empty()) {
return false;
}
value = dataQueue.front();
dataQueue.pop();
return true;
}
bool empty() const {
lock_guard<mutex> lk(mtx);
return dataQueue.empty();
}
};
int main() {
ThreadSafeQueue<int> tsQueue;
// Producer thread.
thread producer([&tsQueue]() {
for(int i = 0; i < 10; ++i) {
cout << 'Producing ' << i << endl;
tsQueue.push(i);
simulateWork(100);
}
});
// Consumer thread.
thread consumer([&tsQueue]() {
for(int i = 0; i < 10; ++i) {
int value;
tsQueue.wait_and_pop(value);
cout << 'Consuming ' << value << endl;
simulateWork(150);
}
});
// Wait for both threads to finish their jobs.
producer.join();
consumer.join();
return 0;
}
Code Output:
The actual output will vary in timing due to the concurrency, but it will be along the lines of:
Producing 0
Consuming 0
Producing 1
Consuming 1
Producing 2
Consuming 2
...
Producing 9
Consuming 9
Code Explanation:
Alright, letās break it down into chewable chunks!
First off, we import necessary libraries like <iostream> for printing stuff to the console, <thread> for multi-threading and dereferencing, and <mutex> to ensure data integrity when threads are duking it out for resources. Weāve got <condition_variable> for thread notification, and <queue> because weāll need a queue structure later on.
The lambda function simulateWork
is a straightforward time-eater ā it simulates some long task by putting the current thread to sleep for a specified duration.
Moving onto the ThreadSafeQueue class, itās a marvel geared towards making sure no two threads go rogue and start messing with our queue simultaneously. The push
method adds a new element and then gives a shout-out to one of the waiting threads with dataCond.notify_one()
.
Then, thereās wait_and_pop
which puts the current thread in chill mode till thereās something to process in the queue. The try_pop
is like wait_and_pop
ās impatient sibling; it doesnāt wait around if the queueās empty.
The main attraction, the main()
function, showcases the producer-consumer model. Our producer is like a digital baker, whipping up freshly baked int cakes and lining them up in the queue. Conversely, the consumerās like that one friend who wonāt stop munching on your snacks, taking whatever the producer puts up.
Lastly, we tie up all loose ends and make sure both threads complete their tasks before wrapping up the show with a producer.join()
and a consumer.join()
. And voilĆ ! Weāve got ourselves a little pocket-sized model of a real-time system with concurrency!
Isnāt it just delightful when complex concepts come together like a well-orchestrated symphony? Keep it locked here for more coding adventures! š
