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.
