Good, and is restriction the transpose?

No, I'm L2-projecting (with mass-lumping) for the restriction. So if I
weren't lumping, I think this is the dual of the prolongation.
A true L2 projection is a dense operation (involves the inverse mass
matrix). But here, we're

Hi Jed,
I removed only one line from the error message that indicated the
unnecessary information like directory path, program name, processor type.
In this problem, I created the vector using VecCreateMPI, not with DM. Does
it cause such problem? I have the unstructured grid and can not use DM

We clearly have the problem that a full stack in not being printed. I am
open to the idea that it is a problem
