PetscSFType

 String with the name of a PetscSF method or the creation function with an optional dynamic library name, for example http://www.mcs.anl.gov/petsc/lib.so:mysfcreate()

Synopsis

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.
