Hello Joe,
I understand the differences between Beowulf and Mosix. With Beowulf,
each process of a "cluster compiled" application can be load balanced
across all clustered servers. With Mosix, each process of an
application or thread will be executed on the cluster node that is least
used (Has resources available). In these types of situations, where
Oh, thanks, this is by far the nicest explanation I've ever read. This
makes perfectly sense now. Thanks.
does LVS fit in? Does an application have to be compiled to use header
files from LVS (aka PVM style)? Is it application independant and more
kernel clustering?
None, actually, IMHO. You define clustering and load sharing, LVS does
traffic load balancing. No processes are involved. It's mainly to have
redundancy and load balancing on the network level. The application
level behind a LVS cluster can then again be load balanced/shared with a
Beowulf/Mosix cluster.
The best situation that I would be looking for is where I wouldn't have
to recompile any applications and that it would load balance
applications (single processes) across multiple nodes.
You can't load balance application load, but you can load balance the
incoming traffic that hits the server those applications are running and
thus indirectly load balance application load but you have almost no
influence on the load balancing of the application load.
I've already decided to go with Mosix unless LVS does a similar thing,
in which case I will probably try LVS instead.
From reading your email I get the impression you definitely need load
sharing and thus either Mosix or Beowulf. I stand corrected but you need
to provide a rough idea of what you intend to do, how does your
application work?
HTH and tell me if it doesn't make sense,
