 C     | SUBROUTINE EXCH_XY_RX                                    |

 C     |==========================================================|  
 C     | Do true shared-memory data transfers and "messaging"     |  
 C     | tranfers for blocking case of data transfers.            |  
 C     | Applications call this routine using                     |  
 C     |  CALL EXCH..( x, myThid )                                |  
 C     | where x is a two-dimensional array with overlaps.        |  
 C     | This routine does true-shared-memory copies for blocks   |  
 C     | within a thread. It will also do MPI meesaging between   |  
 C     | different processes.                                     |
