This places enormous pressure to improve the combustion efficiency in engines for transportation and power generation while simultaneously developing more diverse fuel streams, including carbon neutral biofuels. Ultimately, to shorten the design cycle of new fuels optimally tailored to work with novel fuel efficient, clean engines requires fundamental advances in combustion science. One key avenue of study in this area is the development of predictive models for engineering design. These predictive models couple chemistry with turbulent transport under real world conditions. Exascale computing will enable first principles direct numerical simulation (DNS) of turbulent combustion science at higher Reynolds number, higher pressure, and with greater chemical complexity. One of the primary challenges to achieving exascale computing is designing new architectures that will work under the enormous power and cost constraints. The mission of co-design within the Center for Exascale Simulation of Combustion in Turbulence (ExaCT) is to absorb the sweeping changes necessary for exascale computing into software and ensure that the hardware is developed to meet the requirements to perform these real world combustion computations. ExaCT performs multi-disciplinary research required to iteratively co-design all aspects of combustion simulation including math algorithms for partial differential equations, asynchronous programming environments, scientific data management and analytics for in situ uncertainty quantification. I will present recent results from petascale DNS focusing on mixed regimes of combustion in compression ignition engine environments. I will then present computer science research highlights in ExaCT in the areas of programming environment and runtimes and in situ data analytics. I will conclude with a discussion of prospects for DNS of turbulent combustion at the exascale.
