Erlang gen_server with a large state?

Mochiglobal from mochiweb is designed for exactly this kind of use case. Basically it will take your data structure and compile it into a module, so the data is shared (zero copy for module constants). Only works well on data structures that don't change often, but it sounds like that's what you have.

If your state is changing often implement your model/structure over ETS.

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.
