Re: [K12OSN] Re: MOSIX



Richard:

Let me know if I can help out.  Although, I've proabably done enough damage
this evening...

I'm really interested in fail-over at this point--so one of the clients
doesn't lose their processes when another client is powered off.  I've seen
it happen with a little stress test that I run on one client when the
process gets moved to another.  Power the second client off (with the
migrated process) and the stress test locks up tight on the first box.
(I've probably posted all of this before but it's been a long night! LOL!)

The fail-over factor gets resolved and K12LTSP+OpenMosix (or properly
licensed/authorized MOSIX) and man will things fly!

At any rate, even if you just have two (or more) LTSP servers running *Mosix
(sans *Mosix clients) and the load balancing would be a great boon for
increased perfomance, IMO.  This theory is bourne out when I had the PII
server and a PII client that was running at Runlevel 3 without anyone logged
in on it.  It essentially acted as a load-balancing server in that instance.
