Does anyone have any more information about this?

Is it built on top of MapReduce or is it totally separate from the ground up?

I just checked with my coworker Marko (author of Gremlin [1]) and he told me that no-one really has much info on this. Though he said that Apache Hama [2] + Angrapa [3] is a supposed to be a clone.

I think Hama is built on MR so maybe Google's version is as well?

also check out PIs publications and his thesis http://research.google.com/pubs/author145.html

The lead author will also be giving a presentation on Pregel at SIGMOD 2010: http://www.sigmod2010.org/research_list.shtml

And is the paper from last year available anywhere? Are examples of implementations available?

Apprently this is the paper: http://projects.will.madstones.com/thesis/papers/Malewicz%20...

But it's just 1 page, a bit of a letdown...

http://portal.acm.org/citation.cfm?id=1582716.1582723

only paper I found. It's only a page though!

But it's on the accepted papers list for sigmod/pods 2010, so with luck in a month or so we'll know more. http://j.mp/aPJuyA
