libconcurrentqueue-dev 1.0.3+ds-1 (riscv64 binary) in ubuntu kinetic

 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.

 Reasons to use
 .
 There are not that many full-fledged lock-free queues for C++. Boost has
 one, but it's limited to objects with trivial assignment operators and
 trivial destructors, for example. Intel's TBB queue isn't lock-free,
 and requires trivial constructors too. There're many academic papers
 that implement lock-free queues in C++, but usable source code is hard
 to find, and tests even more so.
 .
 This queue not only has less limitations than others (for the most part),
 but it's also faster. It's been fairly well-tested, and offers advanced
 features like bulk enqueueing/dequeueing (which, with the new design, is
 much faster than one element at a time, approaching and even surpassing
 the speed of a non-concurrent queue even under heavy contention).
