Hello,
 I am trying to understand how the example
libs/graph_parallel/example/breadth_first_search.cpp works. I am not able to
understand (neither find any documentation for it)  the input and output of
the program.
To the best of my understanding a valid input to this program is graph/test/
weighted_graph.gr.
What's the format for the input.

And why does the output of BFS dependent upon the number of process in the
mpirun argument.

Would greatly appreciate any explanation or relevant pointers.

-thanks
Sandeep
