I have a little confusion that perhaps you could clear up for me
1. do the workstation clients act as cluster nodes?
No I'm not using the WS as cluster nodes
2. could they if openmosix patches were applied to the ltsp kernels
Yes but not with OpenMosix, There is another application called KNOPPIX
but the WS need 128MB of memory to display an X -GUI (Some say less
but I have not gotten any to work reliably with less, especially using
Gnome or FDE, with ICEWM it may be possible.
3. would there be any benefit in that
Simply that instead of having the load distributed amongst the servers
ALL the computer in the network would work as one ... hmmm a better
"supercomputer". ;-)

Hola Oscar,
What more would you like to know ? :-)
My basic configuration is K12LTSP 3.1.1 & Openmosix
Server P-IV 2.4Ghz , 1.5GB memory Raid ) 60GB hard drive, 100mbit NIC &
17" monitor
The server hosts all the system applications and user accounts.
Alternate server 1 - P-III 450, 386MB ram, 8GB HD
Alternate server 2 - P-III 733, 1GB ram, 10GB HD
Alternate server 3 - P-II 350, 512 MB ram, 6GB HD
Workstations (20) P-I 100 to 166 mhz, 32 MB ram, floppy drive ( no hard
drive nor CDROM.
System running just on the main LTSP server allows for 6 to 8 concurrent
applications per ws
System running with Openmosix handles 82 to 87 concurrent applications
per ws.
The students have dilengently tried to crash / hack the system but to no
avail. The ONLY thing that has locked / crashed my system is Webmin !!!!
:-D
If you want anymore details just let me know. My next attempt will be
with Sparcstation 5 servers if I can find a Linux distribution for Sparc
that loads on a 540MB Hard Disk or two ...... :-D

May be you can describe some more to us. Thank you.

Asunto: Re: [Ltsp-discuss] Low end machines on LTSP
Hi,
Actually I'd suggest a better server than just 500mhz & 256 mb.
I'm running multiple LTSP setups & the least I'd use is a P-IV
2.4Ghz with 64mb per station plus 256 mb for the server. I have a
20 ws setup with a 4 unit cluster, the only thing that beats this
is running a mini-computer as a server ... ;-)
Good luck..

I am trying to set up network with collection of old machines. Could you
help me for:
1. Pentium I's with 8mb mem get hung up at RAM disk step during boot. I
have enabled nfs_swap option but still the machine does not boot beyond
this. I have four machines of this configuration so I need answers
desperately.
You really need 16MB+ of memory. Memory is cheap so get some used. 32MB is
better.
2. 386's with 8mb mem. I have six machines of this spec and I was
wondering if any of you have made config's for such machines including
running X. I know it will run slow (slower than slow) but till I prove
the concept the management will not sanction upgrades.
I used to run linux (rh4.2) on a 386sx25 back in 1997.
But with kde and gnome, you need more.
Especially if you are going to prove it as a concept running X.
To be impressive, you'll need to show 16-bit minimum color.
Responsive etc.
You haven't even mentioned the server specs, where most of the work is going
on.
Find a decent machine ie. 500MHz min with 256MB ram as the server. Pull the
cable and power connector from the H/D and put a new H/D in. Get linux
running and setup using the LTSP instructions.
Try and find p100Mhz'ish machines with pci slots so you can use a pci graphics
and ethernet cards.
Anything less is going to take more work and won't look impressive if your
demo'ing it.
TIA
Sudev
