CentOS 4 is quite dependent upon 2.6 kernels. Is using CentOS 3 not an option? CentOS 3 uses a 2.4 kernel that could take the openmosix patch.
Well, the head node is already fully configured with Centos4. I figured changing the kernel would be a lot lot easier than replacing the entire OS and reconfiguring everything (configuration being the result of over a years work...)
However, there is a 2.6 openMosix, but it's only available in CVS right now. There are bootable openMosix floppies for instant clusters, as well. Cool stuff.
Yes, I know, however this doesn't _seem_ to be quite production use yet. I probably will try to port the RH patches (if any are even needed) to kernel 2.6.14.4 and then apply openmosix 2.6 on top of that. We'll see when I have the time for this and if it's even possible.
Thanks, MaZe.
