sure, Mosix has been around a while, so is reasonably well-know,
as is Scyld's approach.  what I'm interested in is whether Mosix
functions well in a more-than-toy cluster (say, at least 100p).

I guess I also am uncertain where Mosix's competitive advantage lies.
my experience is that a serial-job workload is so undemanding that 
migration is unnecessary - it's mainly for parallel jobs where you 
really want migration.  (in SHARCnet, there is a strong correlation
for serial jobs to also be relatively short and quite small in memory
use.  not _all_ are, of course, but certainly most.)

regards, mark hahn.
