I think that if you need highest performance, you can probably find
libraries that are faster in shared memory than PBGL (e.g., Ligra, Galois).
Some of these systems are experimental and somewhat harder to use than
PBGL, so you should investigate the performance tradeoff for the particular
use you plan.
