That comes from the MPI implementation -- PBGL doesn't do its own 
communication; it uses Boost.MPI and thus MPI to do it.  You would need to 
set up an MPI implementation (such as Open MPI or MPICH) and give it 
information about your cluster.

I don't think there are any posted online right now.  There will likely be 
some posted within the next month, though.  Note that we are working on a 
new version of PBGL (not released yet) that will be significantly faster; 
<URL:http://doi.acm.org/10.1145/1854273.1854323> has a paper with some of 
those results (including some runs with the current PBGL).
