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
(definitely more experimental than the above, but promising) Kerrighed
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.
