Sorry for wandering off topic here... did I imagine it or did I read
that you'd tried to get 2048 CPUs going in a single system at NASA?

I guess the lack of triumphant press release means it didn't go well,
or that I was imagining things.

Also, are you using 2.6 kernels on these 512 CPU systems? or are your
2.4 kernels still holding together at that many CPUs?
