Here is a webpage. It looks circa 1996, but it's actually from 2006. Enjoy.
If you're looking for the openGR website, it can be found here: http://wwwrel.ph.utexas.edu/openGR/ (Note: The code available for download is a much older version. Please email me if you need the latest code base.)
You may need to right click (or command click on a mac) and download the movies to watch them. Occassionally they cause Safari to crash, so its best to download them and view them with quicktime. They are all in mpeg format.
Incomplete, first run with FMR
Includes patch layout, processor layout, and movies of the conformal factor and Hamiltonian constraint violation
FMR run with restart
Includes patch layout, processor layout, and movies of the conformal factor and lapse. This directory also includes output of the Hamiltonian constraint at T = 15m.

Results from scalability tests of the open source Pregel framework GoldenOrb (Golden Orb)
can be found here:
GoldenOrb (Golden Orb) Scalability
Included in the analysis of GoldenOrb's scalability is a comparison with scalability
results for Google's Pregel
framework and the Apache project for large scale graph
processing, Giraph (which, like GoldenOrb, also provides an open source implementation of the Pregel framework / Pregel API).

The part in bold must be solved for the correct address. To find the solution label each character from 1 to 9 starting from the left. Each characters whose label is a prime number has been rotated by 13 characters in the standard 26 character English alphabet. (Remember: 1 is not a prime number!)
