concurrent_dequeue with {push,pop}_{front,back}

[Customer__Intel6]

Hi,
I am a new TBB user. Is it possible to extend the concurrent_queue to a concurrent_deque having push and pop operations from both front and back?

No, that's completely different containers.

[Customer__Intel6]

Thanks for the reply. I am looking to migrate an existing library using pthreads which has a concurrent_deque to use TBB. Is there any plans to implement the concurrent_deque container in TBB? If not, can you tell me if there is any existing TBB container that could be adapted to mimic the functionality?

--Kannan.

Hi,

I need a dequeue, too. What existing container did you use before? maybe we can use it parallel to intel tbb.

For now, there is no concurrent container in TBB that would allow push() and pop() from two "ends", and no near-term plans to add such. I can only suggest the obvious "use a deque protected with a lock".

It would be interesting to know whether the container being referred to currently provides better performance than a locked deque, or just locking sugar (wrapping each call with a call to the lock).
