No, but now I'm thinking about the early days of Slashdot, when "imagine a beowulf cluster of those" was a common in-joke. Along with the obligatory dozen claiming to be "frist".
I actually learned to code on a Beowulf cluster. The first programs I wrote to completion were on an LP mud that ran on a cluster in the creator's basement. Not because it was necessary for a mud with never more then ten users at once, but just because.
