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.
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.
- Invalid argument. Some argument is invalid and is not identified by a specific error class. This is typically a NULL pointer or
other such error.
- Other error; use MPI_Error_string to get more information about this error code.
- An internal error has been detected. This is fatal. Please send a bug report to the LAM mailing list (see http://www.lam-
MPI_Comm_accept(3), MPI_Comm_connect(3), MPI_Comm_disconnect(3), MPI_Open_port(3)
For more information, please see the official MPI Forum web site, which contains the text of both the MPI-1 and MPI-2 standards. These
documents contain detailed information about each MPI function (most of which is not duplicated in these man pages).
