C *==========================================================* C | Initialisation involves starting up MPI and then joining C | the coupled configuration as a component with the special C | name "Coupler". With the present MIT Coupler library C | only one process can register with the name "Coupler". C | This component is the process responsible for C | coordinating the transfer of data between other C | components and for mapping data from one components C | representation to anothers representation as appropriate.
