Have you seen the book Google's PageRank and Beyond? :)

>> they might be using MapReduce ...

I don't think Map/Reduce is a advanced parallel computing model, but
i'm agree with you.
Have you seen the Hama proposal? (http://wiki.apache.org/incubator/HamaProposal)

I'll presentation ideas about Hama matrix features and some algorithm
strategies at Monday April 21. and Perhaps we could share these
resources by creating the documents on the web as detail as possible.
