[graph-tool] How BIG is your graph

Dear graphErs, I am about to start a project working on a graph with about 50M Nodes and 1B edges and I want your opinion regarding the feasibility of this endeavor with graph_tool. Can you please share your experience with graph examples that were comparable in size? I mostly want to calculate centrality measures and I will need to apply (several) filters to isolate nodes with particular attributes. On top of it, I am running on a super-computer (so memory is NOT an issue) and if I am lucky they have installed/enabled the parallel version of the library. Thank you very much, He
