대규모 순환 버퍼가 있는 공유 메모리 시나리오에서 Boost Interprocess 및 Lockfree를 사용하여 잠금 없는 동기화를 달성하려면 어떻게 해야 합니까?

<code class="cpp">// Shared Memory Types
namespace shm
{
    using shared_string = bip::basic_string<char, std::char_traits<char>, char_alloc>;
    using ring_buffer = boost::lockfree::spsc_queue<
        shared_string, 
        boost::lockfree::capacity<200> 
    >;
}</code>

<code class="cpp">// Consumer Side
int main()
{
    // Open or create shared memory segment
    bip::managed_shared_memory segment(bip::open_or_create, "MySharedMemory", 65536);
    
    // Find or construct shared queue
    shm::ring_buffer *queue = segment.find_or_construct<shm::ring_buffer>("queue")();
    
    // Infinite loop to process messages
    while (true)
    {
        // Sleep for 10ms
        std::this_thread::sleep_for(std::chrono::milliseconds(10));
        
        // Allocate shared string to receive message
        shm::shared_string v(char_alloc);
        
        // Pop message from queue
        if (queue->pop(v))
            std::cout << "Processed: '" << v << "'\n";
    }
}</code>

<code class="cpp">// Producer Side
int main()
{
    // Open or create shared memory segment
    bip::managed_shared_memory segment(bip::open_or_create, "MySharedMemory", 65536);
    
    // Find or construct shared queue
    shm::ring_buffer *queue = segment.find_or_construct<shm::ring_buffer>("queue")();
    
    // Produce messages
    for (const char* s : { "hello world", "the answer is 42", "where is your towel" })
    {
        // Sleep for 250ms
        std::this_thread::sleep_for(std::chrono::milliseconds(250));
        
        // Push message to queue
        queue->push({s, char_alloc});
    }
}</code>
