When to use tbb::concurrent_vector ?

[roderickHuang]

Dear all,

I'm newbe of Intel TBB. When start using tbb, I'm confusing when to use tbb::concurrent_vector, and when std::vector is OK?

After searching some forum (c++ - concurrent_vector for 2d array - Stack Overflow), the question still not clear for me.

Is there any clear notes / examples for when to use tbb::concurrent_vector / std::vector.

Thanks.

Hello @roderickHuang,  you can find detailed documentation for tbb::concurrent_vector in the oneAPI Specification, concurrent_vector.  It is a thread-safe container that allows, e.g., concurrent growth: multiple threads can concurrently grow the container and append new elements. While std::vector is a regular, not thread-safe container.
