MOSIX started in the '70s, on PDP11.  It was ported to linux in the '90s.  It 
is a system for allowing a (pseudo)cluster-wide process id space and 
cluster-wide load balancing via process migration.  OpenMOSIX is a 
fork/re-write of MOSIX that was started a few years ago due to disagreements 
about the MOSIX license (which is not Open Source).  OpenMOSIX is released 
under the GPL, and has a much larger developer and user community than MOSIX.

If you are interested in single-system-image clustering maybe also checkout 
bproc http://sourceforge.net/projects/bproc (note - see scyld for a complete 
bproc solution)
or 
OpenSSI http://www.openssi.org
and
(definitely more experimental than the above, but promising) Kerrighed 
http://www.kerrighed.org/

SSI clusters are certainly interesting, but if you are new to clustering 
you may want to get your feet wet with a more traditional model first, so that 
you have a good reference point when reviewing and weighing options for SSI.
