I would definitely need to see a reference for the Linux kernel. The last time I saw a clustering single system image in Linux it was a hack from the 2.2 kernel in the late 90s. SMP support has been on Linux for nearly ever. I don't known about NUMA.

I've drooled over being able to put together a single system image Linux cluster for years, I've never seen it done with a modern kernel. I've seen attempts that got close, but they didn't even have process migration, the processes would be stuck on whatever nodes they were initially launched on and didn't support checkpoints & restores.

If I could grow a blade system with Infiniband or something to be single system image I'd be wanting to do that right now.
