There was an experiment in the UK to get the public to run climate models on their home PC’s. The big picture was split into chucks they could cope with – probably just a handful of grid points/cells – which they ran for a week. They e-mailed their results to other members of the public to crunch and so on until it was boiled down to something a single machine could handle.
In the US you would have a bigger catchment, about 60 million processors? Makes the Cray’s 1/4 million look modest. What would that do for you?
