Pregel - distributed graph processing | DDI

We're working on 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/) and Phoebus (https://github.com/bhatti/phoebus)

Other potentially interesting frameworks in the area of parallel graph processing: GraphLab (http://www.graphlab.ml.cmu.edu/), HipG (http://www.few.vu.nl/~e.krepska/HipG/), Apache HAMA (http://incubator.apache.org/hama/) and Parallel BGL (http://osl.iu.edu/research/pbgl/)

I haven't heard of any publicly available implementations of Pregel, per se.

The Pregel paper does describe some other related and publicly available frameworks for graph algorithms, but I haven't played with any of those frameworks. Details are in the second last section of the paper: http://www-bd.lip6.fr/ens/grbd2011/extra/SIGMOD10_pregel.pdf
