I interpret this part of your question as meaning that you have already addressed the problem of making your application multi-thread capable. And despite that, it doesn't immediately start using multiple cores.
There are two basic ways to multi-thread in Java. Each logical task you create with these methods should run on a fresh core when needed and available.
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.
