Hi, I am looking at adding full support for exodus to DMPlex (input and output). Until I can understand better the nemesis format (a parallel extension of exodusII), my goal is to be able to scatter data back to cpu 0, re-use the pre-distribution ordering and use the sequential exo library.
I can figure out how to do that using VecScatter but I am intrigued by PetscSF. Is there any documentation available, beside src/vec/is/sf/examples/tutorials/ex1.c? In particular a short description of the basic concepts would be helpful.
