I’m writing, though, in response to your comment about TBB and C. I have over a decade of experience in multithreaded development, usually taking old code written in Fortran and C and applying the traditional low-level threading methods. It’s my view (and I’ll be actively experimenting with this) that wrapping code written in C and other languages with small C++ TBB snippets will be relatively easy and highly efficient. Of course, the ease will depend on the structure of the underlying code (it’s “natural” potential for parallelism).

So, TBB can wrap other code. I also believe that TBB has great potential to be applied for special purposes to create multithreaded libraries that can be called by many other languages. I plan to experiment with this in the very near future as well.
