[Boost-users] PBGL in shared memory

Hi guys, I need to write some graph parallel algorithms and I decided to use boost graph library for this. There are also PBGL. So my question is, is PBGL works great in shared memory environment. My algorithms will be used in a competition, so I know that it will be launched on a single machine, but with quite high number of cores. Is it worth to use sequential BGL with OpenMP or something, PBGL can handle shared memory and prevent overhead from copying data from one process space to another (as I get it is using MPI)?
