SPSCQueue.h A single producer single consumer wait-free and lock-free fixed size queue written in C++11. This implementation is faster than both boost::lockfree::spsc and folly::ProducerConsumerQueue. Example SPSCQueue<int> q(1); auto t = std::thread([&] { while (!q.front()); st...
1. Lock-free SPSC Queue 此处使用一个 RingBuffer 来实现队列。 由于是 SPSC 型的队列,队列头部head只会被 Consumer 写入,队列尾部tail只会被 Producer 写入,所以 SPSC Queue 可以是无锁的,但需要保证写入的原子性。 template<classT>classspsc_queue{private: std::vector<T> m_buffer; std::atomic<size...
A single producer single consumer lock-free queue C++ template for ultimate low latency, which can be used in multithread conmunication as well as in shared memory IPC under Linux. The latency of communication of a 10-200B message is within 50-100 ns between two cpu cores on the same nod...

hot 线程将日志信息提交给 Bounded/Unbounded SPSC Queue,由统一的 Backend 线程去处理。Backend pop SPSC 队列,格式化日志消息保存到一个 buffer 中;为了保持日志顺序,等 SPSC 为空或者 buffer 最大 size 才输出一次日志。实现了类似 spdlog 库一样的可扩展的 Sinks,比如输出到文件、stdout 等。 实现了 Linux ...
②Netty的线程模型决定了taskQueue可以用多个生产者线程同时提交任务,但只会有EventLoop所在线程来消费taskQueue队列中的任务。这样JCTools提供的MpscQueue完全符合Netty线程模式的使用场景。而LinkedBlockingQueue会在生产者线程操作队列时以及消费者线程操作队列时都对队列加锁以保证线程安全性。虽然,在Netty的线程模型中程序...

您可以争辩说,消费中的两个原子负载可能是memory_order_consume。这就放松了约束条件:“我不在乎加载什么顺序,只要它们都在使用时加载”。虽然我在实践中对此表示怀疑,但它带来了任何好处。我也对这个建议感到紧张,因为当我看到boost版本时,它非常接近你所拥有的。queue.hpp ...
