It seems increasingly doubtful that we can reach the exascale destination by incrementalism. Instead, radical innovations in semiconductor processes, computer architecture, system software and programming systems are needed. Simply put, we are facing a chasm of challenges and opportunities that cannot be bridged in small steps. We need a catastrophe – in the mathematical sense – a discontinuity triggered by a sustained research program and development program that combines academia, industry and government expertise.
