Hi there, I am getting lost with the status of PBGL in boost. Is it officially in Boost now ? I am reading some documentation such as: http://charm.cs.uiuc.edu/charmWorkshop/slides/2009_PBGL_Lumsdaine.pptx And it appears there are multiple implementations (see slide #54), namely 'the Parallel BGL' (is there only one?) and the (Parallel) BGL-VTK. Documentation links to : http://www.osl.iu.edu/research/pbgl but this page has not been updated in years, and recent commit AFAIK did happen directly within boost, right ? Is there some threads I am missing, I have been following boost users list but could not find any thread relevant. Basically all I am interested in is how do you provide an iterator interface in a parallel environment where vertex/edge are not local to the machine. Thanks -- Mathieu
