Found it - Xdmx - http://dmx.sourceforge.net/
Note I've never tested that, I only remember I was researching for some alternative to synergy (not allowed at work for security reasons), and found Xdmx (which I don't use anyway).
The only trick - I'm not sure if it's available under ARM...


Very interesting. ARM support, resolutions and lack of current development might be an issue. But very cool project!

One thought though; it's not just about remoting the apps from a single nodes and viewing them on displays connected to the other nodes. We actually want to spread the computational load also and leverage all the nodes properly. I guess one could do both things; have the control node use Xdmx and then still employ the load balancer to run tasks on different nodes but have them redirected back to the master. When they show up they could be moved around the large virtual desktop, but they would not be using the control node's CPU. Hmmm....

What you really need is hot code migration to another machine while the app is running (provided you don't want to kill it) - as much as awesome would that be - I think this is available only in the very high-end cluster solutions/mainframes...

Or VMotion... and by the way, XenServer is being ported to ARM with Pandaboard support. Don't know ETA though.

Xen's xm migrate would do it too. But now we're getting into issues of hypervisor overhead on a relatively modest processor...

That's not what you want. What you want is transparent UNIX process migration from one host to another. It's been done on commodity workstations*, but (so far as I know) only on research operating systems. Though MOSIX might've had something like this, which I guess goes back to the cluster comment...


* Just a handy way to refer to "pizza box" workstations like the early SPARCstations, MIPS DECstations, etc.

Would love to hear your thoughts!


Very impressive!, and I like it a lot!
You know that some people heres bites his lips to keep from screaming, "-Build it in series!" :)

Performance looks very well. Is that an Inventor View session, for the hypercube 3D logo? Any chance to look at it doing anything 2D/3D CAD related? What kind of apps are readily built for ARM? Are Ubuntu's repos same of standard for the ARM platform than for AMD64 and i386? (Sorry, never tried anything ARM related at all.)

If you happen to run short of ideas at any rate :P, I would suggest something like Blender, FreeCAD, or even AOI (Art Of Illusion), K3D, Misfit, etc. doing some interactive modelling!

So, summarizing, looks wonderful!

I am planning on building 10 more units. I have received some interest on PM from a few nekochanners. If anyone would like to sign up to get one, please let me know. You can PM me if you like.

That SGI logo was a video, but I will be running CAD sw and doing another video with a lot more software demos and also views of the case from different angles etc.

Actually Ubuntu support for ARM is pretty darn good and there are a ton of apps available for it. The best part is that the Ubuntu software repository works, so you can simply browse for apps appstore style and double click to install most of them. For stuff in the Canonical sw repository, there's no need to build or cross compile or anything painful like that.

I'll see what CAD sw I can find and will run it to verify.

I used SDcreate to make this image, and used the files from the zip that should work with PandaBoard ES. I can not make claims it works though, as have no way to test myself.

Edit: removed as did not work either...

Very nice, have a good week end!
All the best,

Sadly, this did not work either. I think I am giving up on RiscOS.

I haven't done much further with this project, but here's a video that hasn't been posted before. It shows the internal setup more clearly:

https://www.youtube.com/watch?v=1uTfrfrznqs

I've got an unfinished case and front panel here in Texas and I think I might do a different version with Raspberry Pis at some stage.

What would be really neat, given how the Raspberry Pi's are so small, is if you could keep the Indigo case design but just scale it down to like half or even a third of the size. Hell, it could probably even be (reasonably affordably) 3D printed instead of made of metal :)

Yes, that's a good idea and I have thought about moving to 3D printing and downscaling. It is likely something I will do. When, is another question :-)

I tried to see how printable the existing O2 STL was (was shared on this forum some time ago), but it needs quite a bit of work before it can be readily printed.

I'm sure a little 3D printed raspberry Pi case in the style of something like an Indigo (or indeed other SGI models) would sell quite easily amongst the enthusiast community. God knows, I'd be all over one like a rash really for the novelty factor. And I can't imagine that SGI would pursue you for copyright claims given how they don't manufacture or sell these systems any more.

You can't copyright a case design anyway, the appropriate protection for that is a design patent. and that would be expired now.

You are right.

Here is the Indigo chassis design patent. It was issued for a 14 year term in 1993, and expired in 2007.
