how can we implement a pool/worker structure in gnuradio?

In programming, I need to define a pooling layer that updates the last usrp samples

and other blocks use these pool samples and compute some operations, I emphasize that my means from pool,the pool is shared for all blocks(the blocks that use pool name as worker....)

Can anyone guide me? thanks in advance
