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.)
