Charm++ parallel programming system

[François Tessier <francois.tessier AT inria.fr>]

There is a MPI_Init() at the beginning of the main function in the
application's code. Is it enough to use MPI in my load balancer ?
There is no MPI_Finalize() during the execution. The only one is at the
end of the main function.
