NAME
MPI_Comm_remote_group - Accesses the remote group associated with an intercommunicator. SYNTAX
C Syntax #include <mpi.h> int MPI_Comm_remote_group(MPI_Comm comm, MPI_Group *group) Fortran Syntax INCLUDE 'mpif.h' MPI_COMM_REMOTE_GROUP(COMM, GROUP, IERROR) INTEGER COMM, GROUP, IERROR C++ Syntax #include <mpi.h> Group Intercomm::Get_remote_group() const INPUT PARAMETER
comm Communicator. OUTPUT PARAMETERS
group Remote group of communicator. IERROR Fortran only: Error status (integer). DESCRIPTION
MPI_Comm_remote_group accesses the remote group associated with an intercommunicator. The intercommunicator accessors (MPI_Comm_test_inter, MPI_Comm_remote_size, MPI_Comm_remote_group) are all local operations. 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 ALSO

NAME
MPI_Comm_remote_size - Determines the size of the remote group associated with an intercommunicator. SYNTAX
C Syntax #include <mpi.h> int MPI_Comm_remote_size(MPI_Comm comm, int size) Fortran Syntax INCLUDE 'mpif.h' MPI_COMM_REMOTE_SIZE(COMM, SIZE, IERROR) INTEGER COMM, SIZE, IERROR C++ Syntax #include <mpi.h> int Intercomm::Get_remote_size() const INPUT PARAMETER
comm Communicator (handle). OUTPUT PARAMETERS
size Number of processes in the remote group of comm (integer). IERROR Fortran only: Error status (integer). DESCRIPTION
