What I'm wondering is what apps can you run this way. Why do you use a cluster - mpi or otherwise?
TIA,

cheater way to get LTSP running on hdinstall'ed system
Here is what I did to cheat and get LTSP running on a HD installed Knoppix system( should work for ClusterKnoppix ):
1) boot from the CD and start the LTSP
2) tar up the /tmp/tftp directory and save it to either a hard disk, USB or something persistant
3) boot your HD installed system and start your LTSP session
4) extract the KNOPPIX compressed filesystem from the Knoppix CD to the /cdrom directory
5) un-tar your saved /tmp/tftp data to the local /tmp/tftp system
6) edit the default file in /etc/tftp/pxeconfig directory so that it uses the current IP address
( you can also customize the boot configuration for the PXE boot systems )
Now you should be able to boot a bunch of nodes on your network from your HD installed Knoppix/Debian system. Or ClusterKnoppix. ![Wink](images/smilies/icon_wink.gif)
I'll work on fixing the terminal-server script so this is not needed but in the mean time... enjoy.

Booting via LAN (3C905)starts downloading ClusterKnoppix from the P III, but after a while gives the following error :
"Cant NFSmolunt KNOPPIX filesystem, sorry
Dropping you to a (very limited) shell".
I'm still desperately trying (and browsing forums, sites etc.).
Suggestions?
Well it sounds much lke the regular knoppix i had the same problem the only way i found that worked to fix it was to copy the KNOPPIX dir from the cdrom and place it in the /cdrom folder it worked no problems right away

I'll have to try that since I know copying the /tmp/tftp stuff AND /cdrom works. It would be much easier just copying the CDROM to /cdrom. Thanks for the hint.
One more thing. I had tried mounting the ISO image as /cdromISO and changed all references in the knoppix-terminalserver script from /cdrom to /cdromISO but that didn't work. NFS complained. Being able to run LTSP from a mounted ISO/KNOPPIX would be the best way to run this IMHO. Eventually, I'd like to figure out how to specify LTSP boot images based on either MAC addresses or a list of MAC addresses.

It still seems like there should be a way to get this working completely from a hd install. Copying things to /cdrom is one way, but then you are limited to being able to run only the applications from the cd and not the newly installed ones. What about making /cdrom a symbolic link to /? Is there any way to link /cdrom to the directory structure on a hdinstall and have it work? Just a thought. It seems an easier solution than trying to rewrite the script.

install your applications in /cdrom on your server and you'll find them on every client that boots from the server in the clients /cdrom directory. Not very difficult but it would be nice if the knoppix-terminalserver script was patched on HDD Install to work with a user defined mount point( or directory ). But this'll work too.

So turning /cdrom into a symbolic link for / (or whatever) won't work? How come? I haven't had a chance to give it a try yet.

Symlink
That sounds like a great idea and it is much more effective in the way that things should be done I will have to look into it myself thats what I was hoping for is a way to actually use the same drive as the server

Debian kernel + openmosix patch
I am looking for any documentation on the issue of patching a Debian kernel with the openMosix patch. As stated here the current clusterknoppix kernel is patched from an upcoming openMosix release.
The problems I have is the lack of "root over nfs" and proper support for ext3 and jfs, so I wish to atempt making a kernel with these options.
Has anyone been able to do this?

do you know Quantian, the Scientific Computing Environment
Quantian Scientific Computing Environment
- A Knoppix / Debian variant tailored to numerical and quantitative analysis
it's base on cluster knoppix ![Smile](images/smilies/icon_smile.gif)
a real Live CD linux for science / maths ![Smile](images/smilies/icon_smile.gif)

does anybody know ?
However, Quantian differs from Knoppix by adding a set of programs of interest to applied or theoretical workers in quantitative or data-driven fields. The added quantitative, numerical or scientific programs comprise
