Cluster

I have a network of 7 computers right now setup as 6 windows/linux dual-boot clients and 1 linux server. We are interested in moving from redhat to gentoo on these boxes and running openmosix as we have a researcher who uses idle boxes for simulations that run approx 10 hours. I was wondering (as they range from a p233-athlon xp 1.3) what cflags needed to be used. I assume -march=i686 and -mcpu=localmachine should be alright? These machines run thorough a 10/100 switch and all of them have 10/100 cards, and see that. Any thoughts, comments, etc?

If you use openmosix, USE flags are allowed to be different on different machines. Kernel-versions, (open)mosix-patches and (open)mosix userland tools must be the same version on each machine.

So basically, you can use optimized USE flags on each individual machine without affecting (open)mosix.

In open mosix (and mosix) do the actual binaries migrate (neccesiatating the -march=i686 (lowest common denominator) or does it use the local machines binary?

I think it is the lowest common denominator, but I am not sure... this is what I am asking, as -march generates code that won't go back, but -mcpu will be backwards compatible.

Brought back from the dead..

Any ideas on this? I'm looking to setup a small cluster with a couple of older machines and am unsure which flags to use.

As far as I'm aware, OpenMosix can spread the load of different processes across the cluster. It may be more appropriate to use something such as BeoWulf for a computational cluster.
