PARAMETERS

<IN>  comm   : PMD handel of type PMD_Comm_1D or PMD_Comm_2D.
<OUT> rank   : OPTIONAL parameter. INTEGER scalar. Returns the rank of the calling process.
<OUT> size   : OPTIONAL parameter. INTEGER scalar. Returns the size of the PMD process group.
<OUT> coords : OPTIONAL parameter. INTEGER rank 1 array POINTER. Returns the coordinates
               of the calling process.
<OUT> dims   : OPTIONAL parameter. INTEGER rank 1 array POINTER. Returns the dimensions.
               of the PMD process grid.

EXAMPLES

     USE PMD
     INCLUDE "mpif.h"
     TYPE(PMD_Comm_2D)              :: comm
     INTEGER                        :: info, rank, size
     INTEGER, POINTER, DIMENSION(:) :: coords, dims
     ...
     CALL MPI_INIT( info )
     CALL PMD_Init_1DD( MPI_COMM_WORLD, comm )
     CALL PMD_Comm_Info_1DD( comm, Size=size, Rank=rank )
     ...
     CALL PMD_Comm_Info_1DD( comm, Rank=rank, ProcCoord=coords )
     PRINT *,"My rank and my coordinates in the process grid: ", rank, coords(:)
     ...
     CALL PMD_Comm_Info_1DD( comm, GridDim=dims )
     PRINT *,"The dimensions of the PMD process grid: ", dims(:)
