NAME
MPI_Comm_accept - Establishes communication with a client.SYNTAX
C Syntax
#include <mpi.h> int MPI_Comm_accept(char *port_name, MPI_Info info, int root, MPI_Comm comm, MPI_Comm *newcomm)
Fortran Syntax
INCLUDE 'mpif.h' MPI_COMM_ACCEPT(PORT_NAME, INFO, ROOT, COMM, NEWCOMM, IERROR) CHARACTER*(*) PORT_NAME INTEGER INFO, ROOT, COMM, NEWCOMM, IERROR
C++ Syntax
#include <mpi.h> MPI::Intercomm MPI::Intracomm::Accept(const char* port_name, const MPI::Info& info, int root) const
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. 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.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.
