How to schedule optimally depends on the application, yes.
Just let the user customize the scheduler behavior then.

As for heterogeneous architectures, this is of course an open problem 
that C++ cannot solve because you cannot predict which piece of code 
will be faster on which processor.
But I don't think C++-like languages are unable to do parallelization 
well on heterogeneous architectures, even those with NUMA effects.
