[ILUG] Beowulf's in Ireland

[Jeremiah Russell]

You should read some of the current articles on beowulfs.  The trend seems
to be away from the hypercube towards switched networks (as switches become
cheaper).  An article with a "heads-up" and reference to other sources can
be found at http://news.tucows.com/ext2/articles.shtml.

Regards,

Jerry.
