(http://openssi.org) It comes with a fair amount of user space code as well. Unfortunately, the kernel is moving way faster than they are, so I think the patches are still way back at 2.6.12 or so. They are working on 2.6.16 now I think. I think it is a great project that really needs some kernel developer help. It is basically the functionality of the old Vax Cluster software forward ported, improved, and rewritten, If someone is looking for a truly interesting project to assist on, I would think it would qualify. FYI: It is one of the most "active" clustering projects on sourceforge, so it is not lacking in basic developer support. The problem is that number of issues is just too big for the small team that is working on it.
