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

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

35 If an error occurs in an MPI function, the current MPI error handler is
36 called to handle it. By default, this error handler aborts the MPI
37 job. The error handler may be changed with MPI_Errhandler_set ; the
38 predefined error handler MPI_ERRORS_RETURN may be used to cause error
39 values to be returned (in C and Fortran; this error handler is less
40 useful in with the C++ MPI bindings. The predefined error handler
41 MPI::ERRORS_THROW_EXCEPTIONS should be used in C++ if the error value
42 needs to be recovered). Note that MPI does not guarantee that an MPI
43 program can continue past an error.
44 All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error
46 value; C routines as the value of the function and Fortran routines in
47 the last argument. The C++ bindings for MPI do not return error val‐
48 ues; instead, error values are communicated by throwing exceptions of
49 type MPI::Exception (but not by default). Exceptions are only thrown
50 if the error value is not MPI::SUCCESS .
51 Note that if the MPI::ERRORS_RETURN handler is set in C++, while MPI
54 functions will return upon an error, there will be no way to recover
55 what the actual error value was.
56 MPI_ERR_ARG
57 - Invalid argument. Some argument is invalid and is not identi‐
58 fied by a specific error class. This is typically a NULL
59 pointer or other such error.
60 MPI_ERR_OTHER
61 - Other error; use MPI_Error_string to get more information
62 about this error code.
63 MPI_ERR_INTERN
64 - An internal error has been detected. This is fatal. Please
65 send a bug report to the LAM mailing list (see http://www.lam-
66 mpi.org/contact.php ).

75 For more information, please see the official MPI Forum web site, which
76 contains the text of both the MPI-1 and MPI-2 standards. These docu‐
77 ments contain detailed information about each MPI function (most of
78 which is not duplicated in these man pages).
