The computer and computational science and engineering community in the public, private, and government sectors have been arguably thinking about exascale-class modeling and simulation technologies and capabilities for almost a decade. With exascale platforms becoming more certain and finally within sight, application developers and users must get “get real” now to adequately taken advantage of this opportunity. The hardware and software technologies currently envisioned in exascale platforms will present new challenges for application developers that could be disruptive relative to current approaches. New algorithms, for example, that communicate infrequently and store very little, may be critical for applications to move forward or even “hold pace”. Hybrid node architectures with hierarchical memory and compute technologies will likely be the norm, and applications may face comprehensive restructuring to exploit more appropriate task-based programming models and new data structures.


Given these challenges, tremendous opportunity nevertheless exists for science-based computational applications that can deliver, through effective exploitation of exascale HPC technology, breakthrough modeling and simulation solutions that yield high-confidence insights and answers to the nation’s most critical problems and challenges in scientific discovery, energy assurance, economic competitiveness, and national security. I will survey these application opportunities within the science/energy/national security mission space of the Department of Energy, where I will also touch upon challenges, decadal challenge problems, and prospective outcomes and impact.
