[Boost-users] questions on PBGL

Hello Boost users, I am looking at Parallel Boost Graph Library (PBGL) to check whether it fits our project needs. I have a few questions on PBGL. 1) How does PBGL know about the size of the cluster -- its IP address, name? 2) What is the performance of it -- are there any other numbers apart from ones in the paper http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.107.5681? Thank you. Regards, Raghava.
