Hi,

unfortunately, I can't help you directly with that one as I have no MPI 
installed. I compared your code to one of my attempts to work with 
brandes_betweenness_centrality and I could not find anything that would make me 
say "Change this, and it should work". However, the documentation of 
brandes_betweenness_centrality says for the centrality_map: The value type of 
this property map should be a floating-point or rational type. 
I don't know if you already tried that out. When I eliminate the MPI-parts and 
simply define adjacency_list <vecS, vecS, bidirectionalS, Vertex>, it compiles 
just fine. Also the vector<int> seems not to be a problem, although it might be 
for your results later on.

What is interesting me though is, why you define an internal_vertex_name, when 
you already have it as a bundled property?

Best,

Cedric
