Fixed... We think that is not only a question of increase the range on reverse mode. Increasing the range doesn't allow us to guaranty that the memory accessed will be...

But, anyway, is this analysis valid? Make sense?

@FabioLuporini Thanks for the review. I'll work a little more to add the necessary features so that I can write these adjoint equations using a more compact notation. So, I...

@mloubout Do you have any idea why when we pre-compute (using an auxiliary variable), the` halo` problem disappears?
