Ok thanks for the clarification. In theory, if before the Reduction back to
the original distribution, if I call DMGlobaltoLocal then even with
MPI_REPLACE all the leafs corresponding to the original root should have
the same value so I won't have an ambiguity, correct?

Hi Matt
Yep, that makes sense and is consistent.
My question is a little more specific. So let's say I take an initial mesh
and distribute it and get the distribution SF with an overlap of one.
Consider a cell that is a root on process 0 and a leaf on process 1 after
the distribution.

Hi Petsc Users
I'm working with a distribution start forest generated by
DMPlexDistribute and PetscSFBcast and Reduce to move data between the
initial distribution and the distribution generated by DMPlex Distribute.
I'm trying to debug some values that aren't being copied properly and
wanted to
