 Posted: Sat Jan 17, 2004 6:09 pm Post subject: Questions about openMosix clustering |
 |
|
I've got 2 linux boxes at my school, a G3 and a P2 451 MHz. We're planning to get another P2 this week.
I want to cluster these boxes, but I have a couple questions:
Is that G3 going to cause problems when mixed with x86?
Each box has its own identity on the network (samba and hostname). When they cluster, will those seperate identities vanish into a single cluster, or can they still look like individual boxes over the network?
When clustered, do they only share CPU power? What is shared in the /mfs directory?
How well does the kernel work in normal running if you're not running the cluster daemon? Basically, how is it for regular use?
Can I SSH from one box to the other when they're clustered? Because one is set up headless, so I need to SSH to it to do anything.
Thanks a lot.

Not really. Why? Well, because no arch other than IA32 (x86) is actually supported by openMOSIX. Bummer, eh?

Once you get a "cluster" up and running, you can access each system individually, yes. What the "clustering" does is simply offload tasks to another machine when it's busy. So, you can surf your samba shares to your heart's content.

I'm not actually running a cluster right now, but from the openMOSIX site, it would seem that the /mfs directory would be the root of the "MOSIX File System", which is a filesystem that allows each node in a cluster to access each other node's files, etc. Basically, a computer can't compute without access to data.

Same as above. Each machine is still an individual machine, so you can SSH all you like.

Oh, no. Thank YOU. Hope this helps.
