I have six almost identical machinces 3 compaq evo d500s 2.26, 2.0, 2.0 various ram 1280, 512, 384, and three compaq deskpro en 1.0, 1.0, 1.0, 256, 384, 128. I've been interested in clustering them for awhile, for the purpose of crunching out some seti WUs i've been able to PXE one slave node, but cannot for the life of me get it to join the cluster, or to even see other openmosix systems, the head node sees itself, and the other pxe booted machine sees itself as the cluster soley, if there is a good step-by-step guide for this, or if anyone has any experience and could help me out, please do so

I know little to nothing of open Mosix. I however have read every post ever posted to this message board. That said, Open mosix has been looked into by several people throughout the life of this board, and if memory serves, noone has been able to do it. By searching this board you can locate and see what others have said/tried.

THere is a google search available at the main message board page, but I prefer this message search engine. Good luck in your search. I'd try searching for the Word Mosix or similar in the body of the posts.

has it been made to work on any cluster approach at crunching?

To my very limited understanding of performance clustering ( i.e. beowulf ) you need an app that can share its memory across the cluster nodes to make "collaborative" processing possible. BOINC and the science apps it manages do not support such a memory model ( do they? ) and as such are not clusterable in that fashion.

I may be completely off but I think this is the core of why it is not possible at the moment.

Source code is available for everything so I guess it is up to someone with the know-how, time, and inclination to develop a clusterable framework. The task is beyond my ability to evaluate, but seems daunting.

i heard od this thing called migshm that allows openmosix to migrate seti@home, but since i havn't even gotten other nodes to join my cluster yet, i don't know if i can get that to work

Boinc/Seti@Home is already a distributed solution. I do not see a point of making a distributed-distributed application. Seti@Home is designed to be a single-CPU single-threaded app. The best solution is to simply run independent instances of Boinc on each these nodes.

If the compute nodes in your cluster do not have internet access, consider installing squid on your head node.

the thing is i didn't want to break the 5 computer mark, but now that i have i guess it doesn't matter, i also thought it would be good experience, and from what i hear it would migrates a WU to each processor, also slick.

Hi Slippy,

I've had a try with this long time ago. If you're still interested there's an old thread where you'll find some information.

But in short words, it didn't work for me.
HTH

rattlesnake, i've read that thread more times that i can count... thanks though

Slippy.

I run Fedora with openmosix and use Chaos to connect the nodes to the master running Fedora.

Heres a link: http://www.purehacking.com/chaos/downloads.php

Take a look see, and let me know what you get.

downloading fedora now, is there an RPM for openmosix?

downloading fedora now, is there an RPM for openmosix?

I'm running an older kernel available in i386 rpm format Kernel 2.4.26 Have not had time to try the beta 2.6.15.

Heres where you can download the Kernel and openmosixuser rpm files:

http://sourceforge.net/project/showfiles.php?group_id=46729

I had a very good how to for Red Hat and Mandrake and openmosix. I'll see if I can locate it. Instructions would be the same for fedora.

i've kind of had a love/hate relationship with linux and BSD, never gotten far past the noob stage but i wanted to create this cluster just for crunching seti, and i think i have the knowlege to do it esp with that how-to i'll try it sometime this week and post updates

I've found the pdf's for the fedora cluster and the clusterknoppix cluster using chaos.

The fedora pdf is for fedora core 1 - but should still help with the current fedora core 5.

The links are as follows

Fedora Cluster: http://midnightcode.org/papers/How%20To%20-%20Instant%20openMosix.pdf

For The clusterknoppix setup: http://midnightcode.org/papers/How%20To%20-%20Heterogeneous%20Clusters.pdf

Thanks, I'll be reading both of these tonight, and maybe getting around to setting it up sometime this week
