 The benchmark also requires Intel TBB library to be available. It assumes that it is installed in `/usr/local/include` and `/usr/local/lib`. If it is installed elsewhere you may like to modify `cppflags.tbb` and `ldlibs.tbb` in `Makefile`.

 ## Available queues
 * `AtomicQueue` - a fixed size ring-buffer for atomic elements.
 * `OptimistAtomicQueue` - a faster fixed size ring-buffer for atomic elements which busy-waits when empty or full. It is `AtomicQueue` used with `push`/`pop` instead of `try_push`/`try_pop`.
