Maybe the effort just isn't where you're looking? Intel provides the Threading Building Blocks library for C++; some top notch debugging & profiling tools with multi-threading support; very good documentation; and they do quite a bit of community outreach to educate about and promote multi-threaded programming. (I'm not affiliated with them, just grateful for all of that stuff!)

I'm aware of TBB, but IMHO C++ is not the future of parallel and concurrent programming, or at least not the future I am hoping for.

What is one example of haskell being used effectively for parallel execution in a real world scenario?
