Description
I'm guessing TBB would be the limitation, but to be sure, would it be possible to process R's long vectors in parallel? Since the APIs use size_t in the parallel for-loop, I guess that would not be handled correctly.

Research direction
Start with the parallel for-loop APIs and their size_t handling, then investigate how TBB interacts with R's long vectors. Define whether long vectors can be processed correctly in parallel and identify the required changes before implementation.
