61 : : //! \brief Constructor
62 : : //! \details MeshConv's main chare constructor is the entry point of the
63 : : //! program, called by the Charm++ runtime system. The constructor does
64 : : //! basic initialization steps, e.g., parser the command-line, prints out
65 : : //! some useful information to screen (in verbose mode), and instantiates
66 : : //! a driver. Since Charm++ is fully asynchronous, the constructor
67 : : //! usually spawns asynchronous objects and immediately exits. Thus in the
68 : : //! body of the main chare constructor we fire up an 'execute' chare,
69 : : //! which then calls back to Main::execute(). Finishing the main chare
70 : : //! constructor the Charm++ runtime system then starts the
71 : : //! network-migration of all global-scope data (if any). The execute chare
72 : : //! calling back to Main::execute() signals the end of the migration of
73 : : //! the global-scope data. Then we are ready to execute the driver which
74 : : //! calls back to Main::finalize() when it finished. Then finalize() exits
75 : : //! by calling Charm++'s CkExit(), shutting down the runtime system.
