NAME

       MPI_Win_create -  Create an MPI Window object for one-sided communication

SYNOPSIS

       int MPI_Win_create(void *base, MPI_Aint size, int disp_unit, MPI_Info info,
			 MPI_Comm comm, MPI_Win *win)

INPUT PARAMETERS

       base   - initial address of window (choice)
       size   - size of window in bytes (nonnegative integer)
       disp_unit
	      - local unit size for displacements, in bytes (positive integer)
       info   - info argument (handle)
       comm   - communicator (handle)

OUTPUT PARAMETER

       win    - window object returned by the call (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_ARG
	      - Invalid argument.  Some argument is invalid and is not identified by a specific error class (e.g., MPI_ERR_RANK ).
       MPI_ERR_COMM
	      - Invalid communicator.  A common error is to use a null communicator in a call (not even allowed in MPI_Comm_rank ).
       MPI_ERR_INFO
	      - Invalid Info
       MPI_ERR_OTHER
	      - Other error; use MPI_Error_string to get more information about this error code.
       MPI_ERR_SIZE
	      -

NAME

       MPI_Comm_remote_size -  Determines the size of the remote group	associated with an inter-communictor

SYNOPSIS

       int MPI_Comm_remote_size(MPI_Comm comm, int *size)

INPUT PARAMETER

       comm   - communicator (handle)

OUTPUT PARAMETER

       size   - number of processes in the remote group of comm (integer)

THREAD AND INTERRUPT SAFETY

       This  routine  is  both	thread- and interrupt-safe.  This means that this routine may safely be used by multiple threads and from within a
       signal handler.
