Friday evening (May 15, 2009) was the debut of Stephen Wolfram's "Wolfram Alpha". It officially went public on Monday (May 18, 2009) from the web site at: http://www.wolframalpha.com/index.html According to this article: http://www.hpcwire.com/features/Wolfram-Alpha-Boots-Up-45364022.html Wolfram Alpha employs HPC clusters for its computational hardware. And at launch time, the application had access to about 10,000 x86 CPUs spread across five data-centers. Apparently there are still a few problems to work out, based upon what the article states, but it is interesting to see that queries for fractals can be generated with varying iterations specified.
