PetscSF
PETSc object for setting up and managing the communication of certain entries of arrays and Vecs between MPI processes.
Synopsis
typedef struct _p_PetscSF* PetscSF;
PetscSF uses the concept of star forests to indicate and determine the communication patterns concisely and efficiently.
A star https://en.wikipedia.org/wiki/Star_(graph_theory) forest is simply a collection of trees of height 1. The leave nodes represent
"ghost locations" for the root nodes.
