Combustion Research Facility’s ExaCT Team Completes Several Combustion Proxy Applications

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 Combustion Research Facility‘s 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’s multidisciplinary research will iteratively co-design all aspects of combustion simulation including math algorithms for partial differential equa­tions (PDEs), programming models, scientific data management and analytics for in situ uncertainty quantification and topological analysis, and architectural simulation to explore hardware tradeoffs with combustion proxy applications representing the workload to the exascale ecosystem.

Six DOE laboratories and five university partners (see below) comprise ExaCT—involving the multidisciplinary interaction of combustion scientists, computer scientists, and applied mathematicians. ExaCT is actively developing “proxy apps” that represent key aspects of structured-grid adaptive PDE-based combustion simulations. A subset of these proxy apps are available to the public.
