.SH DESCRIPTION
|
|
.ft R
|
|
MPI_Comm_remote_group accesses the remote group associated with an intercommunicator.
|
|
.sp
|
|
The intercommunicator accessors (MPI_Comm_test_inter, MPI_Comm_remote_size,
|
|
MPI_Comm_remote_group) are all local operations.
|
|
|
|
.SH ERRORS
|
|
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ functions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI:Exception object.
|
|
.sp
|
|
Before the error value is returned, the current MPI error handler is
|
|
called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
