TBB Background
Containers Comparison
List of TBB containers:
concurrent_queue : Multiple threads may simultaneously push and pop elements from the queue.
concurrent_vector :
concurrent_hash_map : hash table that permits concurrent accesses.
quotes: Intel Threaded Building Blocks book. Highly concurrent containers are very important because Standard Template Library (STL) containers generally are not concurrency-friendly, and attempts to modify them concurrently can easily corrupt the containers.

Concept: Fine-grained locking
Multiple threads operate on the container by locking only those portions they really need to lock.
Concept: Lock-free algorithms
Bits of knowledge:
STL interfaces are inherently not thread-safe.
Threading Building Blocks containers are not templated with an allocator argument.
