You're talking about clusters, i.e. multiple running instances of the
operating system. I don't think anybody really wants to go far beyond
512 nowadays. Application-wise 512 cpus/node isn't really needed (but
sometimes nice to have, for marketting). Beyond problems with
scalability of the interconnect (and very uneven latency distribution)
bigger systems would accumulate a too small MTBF. When a broken CPU,
DIMM or other chip takes your entire >1k CPU-machine down, you'll
hapilly exchage it agains a cluster.
