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.
You can find some examples here: https://github.com/boostorg/graph_parallel/tree/master/example You can also look at tests: https://github.com/boostorg/graph_parallel/tree/master/test
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!
