sure,

this is master process, sends objects.

                cin >> a;
                world.send(1, 1, lat);

#RECEIVER PROCESS (rank 1)
Lattice* latr;
printf("worker%2d:: waiting master signal...\n", world.rank());
world.recv(0, 1, latr);
printf("OK\n");
latr->print();


#this is the Lattice class, i have commented almost all atributes on the serialization method except 2 integers.
class Lattice{

#when i send the object it has 
Nodes=2   Edges= 1

#when i receive it, i get
Nodes=131072   Edges= 65536
