Dear all,

I'd like to play with Parallel BGL (with MPI), and I'd like to see some
example code. I've followed the Overview and the Adjacency List example,
but I cannot compile my code.

Right now, I'd like to create a graph, and then fill in with some nodes.
Then, access the nodes belonging to a single process, but I wish I had
an error there

My error concerns the definition of the graph: No template named
'bsp_process_group' in namespace 'boost::parallel'; did you mean
'boost::process_group'? The code follows.

What am I doing wrong here? I may have forgotten some header... Is there
any distributed (complete) example code that I might read?

Thanks & Cheers!

         // access ***only rank 0 nodes***
