NAME

6       MPI_Win_set_attr -  Set attribute on a window
7

SYNOPSIS

9       #include <mpi.h>
10       int
11       MPI_Win_set_attr(MPI_Win win, int key, void* value)
12

INPUT PARAMETERS

14       win    - Window to which the attribute will be attached
15       key    - Key value
16       value  - attribute value

NOTES FOR FORTRAN

20       All  MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have
21       an additional argument ierr at the end of the argument list.   ierr  is
22       an  integer and has the same meaning as the return value of the routine
23       in C.  In Fortran, MPI routines are subroutines, and are  invoked  with
24       the call statement.
25
26       All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in
27       Fortran.

ERRORS

31       If an error occurs in an MPI function, the current MPI error handler is
32       called  to  handle  it.   By default, this error handler aborts the MPI
33       job.  The error handler may be changed with  MPI_Errhandler_set  ;  the
34       predefined  error  handler MPI_ERRORS_RETURN may be used to cause error
35       values to be returned (in C and Fortran; this  error  handler  is  less
36       useful  in  with  the  C++  MPI bindings.  The predefined error handler
37       MPI::ERRORS_THROW_EXCEPTIONS should be used in C++ if the  error  value
38       needs  to  be recovered).  Note that MPI does not guarantee that an MPI
39       program can continue past an error.
40
41       All MPI routines (except MPI_Wtime and  MPI_Wtick  )  return  an  error
42       value;  C routines as the value of the function and Fortran routines in
43       the last argument.  The C++ bindings for MPI do not return  error  val‐
44       ues;  instead,  error values are communicated by throwing exceptions of
45       type MPI::Exception (but not by default).  Exceptions are  only  thrown
46       if the error value is not MPI::SUCCESS .
47
48
49       Note  that  if  the MPI::ERRORS_RETURN handler is set in C++, while MPI
50       functions will return upon an error, there will be no  way  to  recover
51       what the actual error value was.
52       MPI_SUCCESS
53              - No error; MPI routine completed successfully.
54       MPI_ERR_WIN
55              -  Invalid  window.  A common error is to use a null window in a
56              call.
57       MPI_ERR_OTHER
58              - Other error; the error code associated with this  error  indi‐
59              cates an attempt to use an invalue keyval.

69       contains  the  text of both the MPI-1 and MPI-2 standards.  These docu‐
70       ments contain detailed information about each  MPI  function  (most  of
71       which is not duplicated in these man pages).
