TBB concurrent_vector with openmp

Question

Can we use TBB concurrent_vector with openmp?

Will concurrent updates be allowed?

Answer 1

Yes, TBB's concurrent data structures are meant to be thread-safe, which means whatever threading paradigms, such as OpenMP, TBB, Cilk, PPL, and etc, are okay to use TBB's concurrent data structures. This is because concurrent_vector is simply a data structure class rather than threading-related control code.

Furthermore, TBB's mutex can be also used within OpenMP, Cilk, and PPL.
