Name
MPI_Comm_accept - Establishes communication with a client.
Syntax
C Syntax
#include <mpi.h>
int MPI_Comm_accept(const char *port_name, MPI_Info info, int root, MPI_Comm comm, MPI_Comm *newcomm)
Fortran Syntax
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_COMM_ACCEPT(PORT_NAME, INFO, ROOT, COMM, NEWCOMM, IERROR)
CHARACTER*(*) PORT_NAME
INTEGER INFO, ROOT, COMM, NEWCOMM, IERROR
Fortran 2008 Syntax
USE mpi_f08
MPI_Comm_accept(port_name, info, root, comm, newcomm, ierror)
CHARACTER(LEN=*), INTENT(IN) :: port_name
TYPE(MPI_Info), INTENT(IN) :: info
INTEGER, INTENT(IN) :: root
TYPE(MPI_Comm), INTENT(IN) :: comm
TYPE(MPI_Comm), INTENT(OUT) :: newcomm
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
Input Parameters
port_name: Port name (string, used only on root).info: Options given by root for the accept (handle, used only on root). No options currently supported.root: Rank in comm of root node (integer).comm: Intracommunicator over which call is collective (handle).
Output Parameters
newcomm: Intercommunicator with client as remote group (handle)IERROR: Fortran only: Error status (integer).
Description
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, after the
client has connected with the MPI_Comm_accept function using the
MPI_Comm_connect function.
The port_name must have been established through a call to
MPI_Open_port on the root.
Errors
Almost all MPI routines return an error value; C routines as the value
of the function and Fortran routines in the last argument.
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.
