Tera-Scalable Algorithms for Variable-Density Elliptic Hydrodynamics with Spectral Accuracy

We describe Miranda, a massively parallel spectral/compact solver for variabledensity incompressible flow, including viscosity and species diffusivity effects. Miranda utilizes FFTs and band-diagonal matrix solvers to compute spatial derivatives to at least 10th-order accuracy. We have successfully...
