The fork-join framework was implemented in a nice modular fashion so you can just use the work-stealing thread pool.
You could implement a custom BlockingQueue implementation (i think you mainly need to implement the offer() and take() methods) which is backed by a "primary" queue and 0 or more secondary queues. Take would always take from the primary backing queue if non-empty, otherwise it can pull from the secondary queues.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
