The discussion of lack of large-scale bandwidth in supercomputers brings to mind William Kahan's quote "The Fast drives out the Slow, even if the Fast is wrong."; perhaps something like "The Big drives out the Small, even if the Big is useless." might almost apply.
Unfortunately for workloads that have demanding cross-node communication, "bandwidth is only money" is not much comfort when the cost of high all-to-all bandwidth is so great.
