Collective beowulf

[Alan Scheinine]

While I enjoy using Vaxen to denote two Vax computers, on the
sensible side, you should not make Beowulf plural.  In a formal
paper, it is not correct to write "we used conjugate gradient" but
rather the text should be "we used the conjugate gradient technique"
or "conjugate gradient iterative approximation" beause the words
"conjugate gradient" are used as an adjective in this case.
Similarly, you would have several Beowulf clusters.
