So, now i have:

struct centrality_t {
typedef vertex_property_tag kind;
};

typedef property<centrality_t, double> VertexCentrality;

typedef boost::adjacency_list<listS,
distributedS<mpi_process_group,vecS>,
undirectedS, VertexCentrality> Graph;

typedef boost::unique_rmat_iterator<boost::minstd_rand, Graph> RMATGen;

struct no_self_loops
{
no_self_loops() {}
bool operator()(const std::pair<int,int>& e) { return e.first != e.second; }
};

template <typename G>
struct VertexKey
{
typedef int value_type;
typedef typename graph_traits<G>::vertex_descriptor key_type;
typedef read_write_property_map_tag category;
typedef int* reference;
};

int main(int argc, char* argv[])
{
boost::mpi::environment env(argc, argv);
boost::minstd_rand gen;
unsigned int SCALE = atoi(argv[1]);
unsigned int EDGE_FACTOR = atoi(argv[2]);
unsigned int N = pow(2, SCALE);
unsigned int E = EDGE_FACTOR * N;

Graph g(
boost::make_filter_iterator<no_self_loops>
(
RMATGen(gen, N, E, 0.45, 0.15, 0.15, 0.25), RMATGen()),
boost::make_filter_iterator<no_self_loops>(RMATGen(), RMATGen()),
N);

typedef boost::property_map<Graph, centrality_t>::type LocalMap;

typedef boost::parallel::distributed_property_map<mpi_process_group,
LocalMap, VertexKey<Graph> > CentralityMap;

LocalMap local_map = get(centrality_t(), g);

mpi_process_group process_groupe;

 //VertexKey<Graph> vertex_key;

CentralityMap centrality_map(process_groupe, local_map);

//brandes_betweenness_centrality(g, centrality_map);
}

network.cpp: In function ‘int main(int, char**)’:
network.cpp:78: error: no matching function for call to ...
/opt/boost_1_54_0_icc/boost/property_map/parallel/

distributed_property_map.hpp:329: note: candidates are:
boost::parallel::distributed_property_map<ProcessGroup, GlobalMap,
StorageMap>::distributed_property_map(const ProcessGroup&, const
GlobalMap&, const StorageMap&)

Is this right arguments  centrality_map(process_groupe, local_map) ?

Or it must be:
VertexKey<Graph> vertex_key;

CentralityMap centrality_map =
boost::parallel::make_distributed_property_map(process_groupe, local_map,
vertex_key);

In this case:
network.cpp:78: instantiated from here
/opt/boost_1_54_0_icc/boost/property_map/parallel/impl/distributed_property_map.ipp:140:
error: request for member ‘first’ in ‘p’, which is of non-class type

/opt/boost_1_54_0_icc/boost/property_map/parallel/impl/distributed_property_map.ipp:142:
error: request for member ‘second’ in ‘p’, which is of non-class type

Any suggestions?

Thanks.
