Technical Perspective: Graphs, Betweenness Centrality, and the GP­U

"Accelerating GPU Betweenness Centrality" by McLaughlin and Bader ably addresses the challenges to authors of efficient graph implementations in the important context...

Accelerating GP­U Betweenness Centrality
From Communications of the ACM

Accelerating GP­U Betweenness Centrality

We present a hybrid GPU implementation that provides good performance on graphs of arbitrary structure rather than just scale-free graphs as was done previously...
