This code is running successfully at multiple user locations. A special
thanks goes to Helen Chen and her team at Sandia Labs for their help
in resolving multiple usability and stability issues. The code in the current
release was used to produce the results reported in their presentation
at the recent Commodity Cluster Computing Symposium in Baltimore.
