I have got a problem.
I have to decide if i use shared memory and risk bank conflicts, or make use of atomic functions.
The algorithem is not deterministic, so i have no chance to evade bank conflicts with help of padding or a well designed accses pattern. Its a kind of union find algorithem.
So whats the better decision use atomics, nearly in every thread, or risk some Bank conflicts ?
thanks for help and im sorry for my bad english.
