Linux Parallel Processing HOWTO

Hank Dietz, hankd at engr.uky.edu

Although this HOWTO has been "republished" (v2.0, 2004-06-28) to update the author contact info, it has many broken links and some information is seriously out of date. Rather than just repairing links, this document is being heavily rewritten as a Guide which we expect to release in July 2004. At that time, the HOWTO will be obsolete. The prefered home URL for both the old and new documents is http://aggregate.org/LDP/
