We're working on Signal/Collect (http://code.google.com/p/signal-collect/ http://code.google.com/p/signal-collect/), a parallel graph processing framework with a set of features that is similar to Pregel. Other projects that are closely related to Pregel: Menthor (http://lcavwww.epfl.ch/~hmiller/menthor/ http://lcavwww.epfl.ch/~hmiller/menthor/) and Phoebus (https://github.com/bhatti/phoebus https://github.com/bhatti/phoebus) Other potentially interesting frameworks in the area of parallel graph processing: GraphLab (http://www.graphlab.ml.cmu.edu/ http://www.graphlab.ml.cmu.edu/), HipG (http://www.few.vu.nl/~e.krepska/HipG/ http://www.few.vu.nl/~e.krepska/HipG/), Apache HAMA (http://incubator.apache.org/hama/ http://incubator.apache.org/hama/) and Parallel BGL (http://osl.iu.edu/research/pbgl/ http://osl.iu.edu/research/pbgl/)
