NAME

       MPI_Type_create_subarray   -    Create   a   datatype   for   a  subarray  of  a  regular,
       multidimensional array

SYNOPSIS

       int MPI_Type_create_subarray(int ndims,
                                  const int array_of_sizes[],
                                  const int array_of_subsizes[],
                                  const int array_of_starts[],
                                  int order,
                                  MPI_Datatype oldtype,
                                  MPI_Datatype *newtype)

INPUT PARAMETERS

       ndims  - number of array dimensions (positive integer)
       array_of_sizes
              - number of elements of type oldtype in each dimension of the full array (array  of
              positive integers)
       array_of_subsizes
              -  number  of  elements of type oldtype in each dimension of the subarray (array of
              positive integers)
       array_of_starts
              - starting coordinates of the subarray in  each  dimension  (array  of  nonnegative
              integers)
       order  - array storage order flag (state)
       oldtype
              - array element datatype (handle)

OUTPUT PARAMETERS

       newtype
              - new datatype (handle)

THREAD AND INTERRUPT SAFETY

       This  routine is thread-safe.  This means that this routine may be safely used by multiple
       threads without the need for any user-provided thread locks.  However, the routine is  not
       interrupt  safe.   Typically, this is due to the use of memory allocation routines such as
       malloc or other non-MPICH runtime routines that are themselves not interrupt-safe.

NOTES FOR FORTRAN

       All MPI routines in Fortran (except for MPI_WTIME  and  MPI_WTICK  )  have  an  additional
       argument  ierr  at  the  end  of  the  argument list.  ierr is an integer and has the same
       meaning as the  return  value  of  the  routine  in  C.   In  Fortran,  MPI  routines  are
       subroutines, and are invoked with the call statement.

       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.

ERRORS

       All  MPI  routines  (except MPI_Wtime and MPI_Wtick ) return an error value; C routines as
       the value of the function and Fortran routines in the last argument.  Before the value  is
       returned,  the current MPI error handler is called.  By default, this error handler aborts
       the MPI  job.   The  error  handler  may  be  changed  with  MPI_Comm_set_errhandler  (for
       communicators),  MPI_File_set_errhandler  (for files), and MPI_Win_set_errhandler (for RMA
       windows).  The MPI-1 routine MPI_Errhandler_set may be used but  its  use  is  deprecated.
       The  predefined  error  handler  MPI_ERRORS_RETURN may be used to cause error values to be
       returned.  Note that MPI does not guarentee that an  MPI  program  can  continue  past  an
       error; however, MPI implementations will attempt to continue whenever possible.

       MPI_SUCCESS
              - No error; MPI routine completed successfully.
       MPI_ERR_TYPE
              -  Invalid datatype argument.  Additionally, this error can occur if an uncommitted
              MPI_Datatype (see MPI_Type_commit ) is used in a communication call.
       MPI_ERR_ARG
              - Invalid argument.  Some argument is invalid and is not identified by  a  specific
              error class (e.g., MPI_ERR_RANK ).
