String with the name of a PetscSF method or the creation function with an optional dynamic library name, for example


typedef const char *PetscSFType;
#define PETSCSFBASIC  "basic"
#define PETSCSFWINDOW "window"

Notes: 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.
