Adaptive computational fluid dynamics -

Quinoa is a set of computational tools that enables research and numerical analysis in fluid dynamics. Using the Charm++ runtime system, we employ asynchronous (or non-blocking) parallel programming and decompose computational problems into a large number of work units (that may be more than the available number of processors) enabling arbitrary overlap of parallel computation, communication, input, and output. Then the runtime system dynamically and automatically homogenizes computational load across the simulation distributed across many computers.

Our ultimate goal is to simulate large and complex engineering multiphysics problems with a production-quality code that is extensible and maintainable, using hardware resources efficiently, even for problems with a priori unknown, heterogeneous, and dynamic load distribution.

This software has been acknowledged by the U.S. Department of Energy / National Nuclear Security Administration for open source release, C20072.
