[ubuntu-uk] Virtualisation and ClientsClinets was High Performance Computing

[Ian Pascoe]

I admit I'm being lazy here, but is it possible to run different OS's from
the same server - virtualisation - out to a thin client processor?

I have just seen some niffty thin client processors at work, and wondered
about the ability to do this so that when the LUG gives public dmos, for
example, everything is on one server and it's that server that just needs to
update itself.

Just an idea to bounce around and get some feedback on please y'all.

Ian

Comparing PVM and MOSIX is an "apples and oranges" comparison, to some
extent.

As I understand it: MOSIX and OpenMOSIX are generally designed to run
applications unmodified.  PVM, on the other hand, needs applications
specifically written under the PVM framework, i.e. there are 'pvm_*'
function calls in your code.

PVM may well be more powerful, but it's scope is more limited.
