+Defines how MPI handles the exchange of ghost points. By default ({{{.F.}}}), asynchronous transfer with {{{MPI_ISEND}}} and {{{MPI_IRECV}}} is used. In case of '''synchronous_exchange''' = {{{.T.}}} {{{MPI_SENDRECV}}} is used instead. On most networks the asynchronous method will give better performance.
