According to news from the trenches, 1 kNodes nowadays is not considered
large anymore. There is a distinct trend to more dense packaging, and
advent of first fully solid state clusters. Custom high-speed
interconnects are getting better, but Ethernet and GBit Ethernet appears
to be dominating for price/performance for budget clusters.
This trend should hold for the next half decade, with advent of 64 bit low
end and built-in message passing, plus multi-CPU modules.

I don't know about this local disk thing. The next cluster we build (1024
node) won't have 'em. Cplant@sandia.gov, an 1824-node cluster, doesn't
have them.
What do you use local disk for?

our next, 1024-node cluster, will be linuxbios-based. As we learned on our
128-node Alpha cluster, linuxbios helps a whole lot ...
