Do We Underestimate the Real Challenge of Exascale?

Over at the ISC Blog, Mark Parsons from the EPCC supercomputing centre writes that scalable software is the real Grand Challenge of Exascale.

I believe that the problems that we’ve seen at the Petascale with regard to the scaling of many codes are insurmountable if we take the incremental change approach at the Exascale. Looking at the CRESTA codes, it is highly unlikely any of them will scale to the Exascale, even allowing for weak scaling (through increased resolution of the model under study) using incremental improvements. This means we need to think about disruptive changes to codes in order to meet the challenge.
