In this example, Zoltan_Initialize is called using the argc and argv arguments to the main program. Then a pointer to a Zoltan structure is returned by the call to Zoltan_Create. In this example, all processors will be used by Zoltan, as MPI_COMM_WORLD is passed to Zoltan_Create as the communicator.
Several application query functions are then registered with Zoltan through calls to Zoltan_Set_Fn. Parameters are set through calls to Zoltan_Set_Param. The application then performs in computations, including making calls to Zoltan functions and utilities.
Before its execution ends, the application frees memory used by Zoltan by
|/* Initialize the Zoltan library
struct Zoltan_Struct *zz;
Zoltan_Initialize(argc, argv, &version);
zz = Zoltan_Create(MPI_COMM_WORLD);
/* Register query functions. */
/* Set some Zoltan parameters. */
/* Perform application computations, call Zoltan, etc. */
/* Free Zoltan data structure before ending application. */
|! Initialize the Zoltan library

ierr = Zoltan_Initialize(version) ! without argc and argv
zz => Zoltan_Create(MPI_COMM_WORLD)
! Register load-balancing query functions.
! Set some Zoltan parameters.
! Perform application computations, call Zoltan, etc.
! Free Zoltan data structure before ending application.
