    ……

    xclient := client.NewXClient("Arith", client.Failover, client.RoundRobin, d, client.DefaultOption)
    defer xclient.Close()

    args := &example.Args{
        A: 10,
        B: 20,
    }

    for {
        reply := &example.Reply{}
        err := xclient.Broadcast(context.Background(), "Mul", args, reply)
        if err != nil {
            log.Fatalf("failed to call: %v", err)
        }

        log.Printf("%d * %d = %d", args.A, args.B, reply.C)
        time.Sleep(1e9)
    }
