I wonder if having one supercomputer with x number of chips or having eight supercomputers each with x/8 number of chips would be the more practical working setup. Weather forecasting for example is basically a complex probabilistic algorithm, and there's a notion that running eight models in parallel and then comparing and contrasting the results will give better estimates of actual outcomes than running one model on a much more powerful machine.

Is it feasible to run eight models on one supercomputer, or is that inefficient?
