Afternoon all,
I don't know how many people this affects, but I thought it was
worth posting in case people are using openMosix. The
leader of openMosix, Moshe Bar, has announced that the
openMosix project is ending.

While I haven't used openMosix, I've seen it used and it is
pretty cool to see processes move around nodes.
Yeah, but it has nearly always had a few tragic flaws. One was that it
was always basically a hack of a specific kernel version and image,
meaning that if you used it you were outside of a working kernel update
stream. The second was that it was basically a hack of a specific
kernel version and image at all, where one really would prefer a tool
that did the same thing outside of kernel space (like Condor, for
example). It survived those flaws, of course -- but it cannot survive
the advent of virtualization, which will provide new pathways for this
sort of thing to be done with far greater ease and stability.
Hello, Robert.
I've been using openMosix for a long time, and you're right about the
kernel 'trap' it puts you into. I recently 'ported' linux-2.4.26-om1 to
Ubuntu. Although I've succeeded in getting our 92-node Beowulf up and
running openMosix under Ubuntu 6.06.1 LTS the end of life announcement
means I have to start thinking about replacing it.
Do you really think that Condor is an alternative to openMosix?
I don't know much about Condor, but I thought is was a DRM (Distributed
Resource Manager) like SGE. Is it more than that?
The great thing about openMosix is that most 'ordinary' programs
migrate. I've thought about using openSSI previously: What's your
opinion about that for 'embarrassingly' parallel computation?
Best wishes,
Tony.
