ABSTRACT: High-performance computing has gone through numerous cycles in the never-ending quest for higher performance. Today, several of these cycles—in technical, social, and commercial realms—are converging to present a real challenge to reaching exascale-class computing. Numerous technical realities, including hitting the power/performance wall for commodity processors, limits on programming models and languages, and the often-announced end of the run for Moore’s law, are conspiring to make the road to exascale computing a steep climb. Unlike reaching a petaflops, attaining exascale performance requires new programming paradigms, hardware architectures, and interconnects. This talk will discuss a little bit of déja vu (what got us here), some of today’s technologies that will get us to exascale computing (including heterogeneous computing models), and some specific recommendations and examples.
