|
newcomm

.SH DESCRIPTION
|
|
.ft R
|
|
MPI_Comm_accept establishes communication with a client. It is collective over the calling communicator. It returns an intercommunicator that allows communication with the client.
|
|
.sp
|
|
The \fIport_name\fP must have been established through a call to MPI_Open_port on the root.
|
|
|
|
.SH SUPPORTED INFO KEYS
|
|
None.
|
|
|
|
.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.
|
|

See the MPI man page for a full list of MPI error codes.
