A lock-free multi-producer multi-consumer ring buffer FIFO queue.

LockFreeQueue

Here, I am testing some multi-producer multi-consumer bounded ring buffer FIFO queue implementations for fun.

• LockFreeQueueCpp11.h - The fastest lock free queue I have managed to implement.
• LockFreeQueue.h - The fastest lock free queue I have managed to implement without c++11. It is equally fast as LockFreeQueueCpp11.h.
• mpmc_bounded_queue.h - Bounded MPMC queue by [Dmitry Vyukov, 2011]
• LockFreeQueueSlow1.h - My first attempt at implementing a lock free queue. It is working correctly, but it is a lot slower than LockFreeQueue.h.
• LockFreeQueueSlow2.h - A lock free queue based on [John D. Valois, 1994]. The queue uses Valois' algorithm adapted to a ring buffer structure with some modifications to tackle the ABA-Problem.
• LockFreeQueueSlow3.h - Another lock free queue almost as fast as LockFreeQueue.h.
• MutexLockQueue.h - A naive queue implementation that uses a conventional mutex lock (CriticalSecion / pthread-Mutex).
• SpinLockQueue.h - A naive queue implementation that uses an atomic TestAndSet-lock.

And for the fun of it, here is a multi-producer multi-consumer LIFO queue:

• LockFreeLifoQueue.h - A lock free multi-producer multi-consumer bounded LIFO queue.
