Parallel, Scalable Parabolized Navier-Stokes Solver for Large-Scale Simulations

A massively parallel formulation for the solution of the parabolized Navier-Stokes equations has been developed for multiple instruction, multiple data (MIMD) computers. All functionality of the serial version of the code has been preserved in the parallel implementation, including grid generation, linear system solvers, and shock fitting. The computational domain is automatically decomposed and load balanced on individual processing elements. Performance timings are carried out for various MIMD architectures. Numerical tests indicate high parallel efficiency, with fixed solution time as the computational work is scaled with the number of processors. 13 refs.
