NAME

       MPI_Put -  One Sided data placement operation

SYNOPSIS

       #include <mpi.h>
       int
       MPI_Put(void *orgaddr, int orgcnt, MPI_Datatype orgtype, int rank,
               MPI_Aint targdisp, int targcnt, MPI_Datatype targtype, MPI_Win win)

INPUT PARAMETERS

       orgaddr
              - initial address of origin buffer (choice)
       orgcnt - number of entries in origin buffer (nonnegative integer)
       orgtype
              - datatype of each entry in origin buffer (handle)
       rank   - rank of target (nonnegative integer)
       targdisp
              - displacement from start of window to target buffer (nonnegative integer)
       targcnt
              - number of entries in target buffer (nonnegative integer)
       targtype
              - datatype of each entry in target buffer (handle)
       win    - window object used for communication (handle)

NOTES

       The  target_datatype  argument  is  a  handle  to a datatype object that is defined at the
       origin process, even though it defines a data layout in the target process memory.

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.

USAGE WITH IMPI EXTENSIONS

       The  IMPI  standard  only supports MPI-1 functions.  Hence, this function is currently not
       designed to operate within an IMPI job.

ERRORS

       If an error occurs in an MPI function, the current MPI error handler is called  to  handle
       it.   By default, this error handler aborts the MPI job.  The error handler may be changed
       with MPI_Errhandler_set ; the predefined error handler MPI_ERRORS_RETURN may  be  used  to
       cause  error values to be returned (in C and Fortran; this error handler is less useful in
       with the C++ MPI bindings.   The  predefined  error  handler  MPI::ERRORS_THROW_EXCEPTIONS
       should  be  used in C++ if the error value needs to be recovered).  Note that MPI does not
       guarantee that an MPI program can continue past an error.

       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.  The C++ bindings for
       MPI do not return error  values;  instead,  error  values  are  communicated  by  throwing
       exceptions of type MPI::Exception (but not by default).  Exceptions are only thrown if the
       error value is not MPI::SUCCESS .

       Note that if the MPI::ERRORS_RETURN handler is set in C++, while MPI functions will return
       upon an error, there will be no way to recover what the actual error value was.
       MPI_SUCCESS
              - No error; MPI routine completed successfully.
       MPI_ERR_WIN
              - Invalid window.  A common error is to use a null window in a call.
       MPI_ERR_RANK
              -  Invalid  source or destination rank.  Ranks must be between zero and the size of
              the  communicator  minus  one;  ranks  in  a  receive  (  MPI_Recv  ,  MPI_Irecv  ,
              MPI_Sendrecv , etc.) may also be MPI_ANY_SOURCE .

       MPI_ERR_OTHER
              - Other error; use MPI_Error_string to get more information about this error code.
       MPI_ERR_EPOCH
              -  This  error indicates than an operation has been attempted on a "closed" window.
              Certain one-sided operations can only be performed on windows whose epoch has  been
              started with MPI_Win_start.
       MPI_ERR_INTERN
              - An internal error has been detected.  This is fatal.  Please send a bug report to
              the LAM mailing list (see http://www.lam-mpi.org/contact.php ).
       MPI_ERR_TYPENOTSUP
              - Type not  supported  for  this  operation.   This  typically  applies  to  either
              reduction  operations  (for  which  only  a  limited  combination  of datatypes and
              operations are defined, see MPI-1, section 4.9.2) or one-sided operations where the
              actions on specific datatpyes have not been implemented yet.
