MPI_Lookup_name(3OpenMPI)												 MPI_Lookup_name(3OpenMPI)

NAME
MPI_Lookup_name - Finds port associated with a service name SYNTAX
C Syntax #include <mpi.h> int MPI_Lookup_name(char *service_name, MPI_Info info, char *port_name) Fortran Syntax INCLUDE 'mpif.h' MPI_LOOKUP_NAME(SERVICE_NAME, INFO, PORT_NAME, IERROR) CHARACTER*(*) SERVICE_NAME, PORT_NAME INTEGER INFO, IERROR C++ Syntax #include <mpi.h> void MPI::Lookup_name(const char *service_name, const MPI::Info& info, char* port_name) INPUT PARAMETERS
service_name A service name (string). info Options to the name service functions (handle). No options currently supported. OUTPUT PARAMETERS
port_name a port name (string). IERROR Fortran only: Error status (integer). DESCRIPTION
This function retrieves a port_name published under service_name by a previous invocation of MPI_Publish_name. The application must supply a port_name buffer large enough to hold the largest possible port name (i.e., MPI_MAX_PORT_NAME bytes). The info parameter should be MPI_INFO_NULL, as this routine does not parse any MPI Info arguments. 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++ func- tions 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. Note that MPI does not guarantee that an MPI program can continue past an error. See the MPI man page for a full list of MPI error codes. SEE ALSO

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++ func- tions 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.
