Also, the following Internet resources have been a source of inspiration for this project:
http://beowulf.gsfc.nasa.gov/
The homepage of the Beowulf project at NASA. Especially the associated
Beowulf mailing list is interesting as it is regularly a source of
good cluster computing discussions.
http://cnls.lanl.gov/avalon/
One of the many examples of what is possible with cluster computing.
This is the homepage of a 140 processor Alpha based cluster. This is
47.7 GFLOPS on a Linpack benchmark, for $ 300.000 in 1998.
The TONS project has a homepage at http://www.sslug.dk/TONS/. The source code for the latest released implementations is also available there for download. The homepage is kindly hosted by Skåne/Sjælland Linux User Group.
