Rajat,
I am using the GridGenerator::hyper_rectangle function to create a > rectangular grid with 1000 X 500 X 1 (0.5 million) elements. > > My question is: - since the coarsest mesh contains 0.5 million elements, > does that mean all the processors have 0.5 million elements? > (I think the answer is yes, I read that the deal.ii (p4est) stores the > coarsest mesh on all processors.) > Yes, that is true. I need a mesh (overall) which should be rectangular and should have 1000 X > 500 X 1 elements. Note: It should only have 1 element in the z-direction. > Is there any way such that I can have this mesh by not replicating the > whole mesh on all processors as it takes a lot of memory.

This means that you can get 1 element in z-direction if you don't refine. There is some work [1] on a Triangulation that allows you to specify the distribution of cells across processes yourself without the need of a common coarse mesh.
