Massively parallel MIMD solution of the parabolized Navier-Stokes equations

Reaching new milestones in science and engineering will require the speed and scalability offered by massively parallel computers. The primary challenge to the users of this technology will be the development of scalable software. All the software's functionality, including the generation of grids, the algorithmic solvers, and the production of output for interpretation and visualization, must scale across multiple processors. As an example of the scalable application concept, the authors have developed a highly parallel, scalable version of a parabolized Navier-Stokes (PNS) code used to simulate steady three-dimensional flow past supersonic and hypersonic flight vehicles. The primary goal of this research has been to develop a fully scalable version of the PNS procedure and to demonstrate that it can achieve high performance on a massively parallel, multiple instruction multiple data (MIMD) computer.<>
