Interesting.. In any case, the book is a recent new translation of the epic
poem written around 1000 years ago. Much more readable, but also of no
connection to beowulf (the cluster computing).

You'd have to ask Don Becker about that. He chose the name when he built the
first one a few years ago.  http://www.beowulf.org/ has a little history.

Oh.. That's a bit more difficult. And, you're right, the Wikipedia entry
isn't necessarily the best way to go about it.  Asking here on the list is
probably a better way. If you describe your problem, then folks will most
likely respond with their opinions of what sort of computational
architecture is well suited.  Opinions WILL differ, but I think everyone
here will justify their opinion (some at more length than others) and you
can use that to see if it's applicable to your particular problem.

You've got that right.  This *is* the place to ask.

Gosh.. No offense at all. But you should be aware that "beowulf" is a fairly
generic description of a general approach to computing, so there's no
"Beowulf software" in the sense of a particular installable program or set
of programs or a Linux distro.

Check out Robert G. Brown's book online.. (there's a link on the
http://www.beowulf.org/ site, if you can't find it elsewhere)
