I wish I could give you a ready-made solution, but the multi-threaded systems 
I've worked on in the past decade were designed so that most of the development 
team could concentrate on single-threaded problems.  Only a couple of people 
needed to understand the load-balancing/scheduling code, and I was not one of 
them.

I can point to the C++11 thread support and atomic operations libraries:

        https://en.cppreference.com/w/cpp/thread
        https://en.cppreference.com/w/cpp/atomic

Anything else I might say would be speculative.  I'd probably start with the 
std::thread class.
