String with the name of a PetscSF method or the creation function with an optional dynamic library name, for example https://www.mcs.anl.gov/petsc/lib.so:mysfcreate()
typedef const char *PetscSFType;
#define PETSCSFBASIC "basic"
#define PETSCSFWINDOW "window"
The two approaches provided are
PETSCSFBASIC which uses MPI 1 message passing to perform the communication and
PETSCSFWINDOW which uses MPI 2 one-sided operations to perform the communication, this may be more efficient,
but may not be available for all MPI distributions. In particular OpenMPI has bugs in its one-sided
operations that prevent its use.
