concurrentqueue/1.0.3+7

A fast multi-producer, multi-consumer lock-free concurrent queue for C++11

An industrial-strength lock-free queue for C++.

Note: If all you need is a single-producer, single-consumer queue, I have one of those too.

Features

Knock-your-socks-off blazing fast performance.
Single-header implementation. Just drop it in your project.
Fully thread-safe lock-free queue. Use concurrently from any number of threads.
C++11 implementation -- elements are moved (instead of copied) where possible.
Templated, obviating the need to deal exclusively with pointers -- memory is managed for you.
No artificial limitations on element types or maximum count.
Memory can be allocated once up-front, or dynamically as needed.
Fully portable (no assembly; all is done through standard C++11 primitives).
Supports super-fast bulk operations.
Includes a low-overhead blocking version (BlockingConcurrentQueue).
Exception safe.
