Numerical Flow Simulation and Rendering Using MPI

In this paper, results obtained with a parallel computational uid dynamics (CFD) simulation code with an embedded parallel rendering library are presented. By linking the rendering library into the CFD code, visualization of CFD data can be done at runtime. Several factors make in-place rendering of CFD data preferable to the use of external rendering packages or dedicated graphics workstations. One of the biggest advantages in doing rendering in-place is avoiding significant I/O overhead typically incurred when moving CFD data to disk les or remote systems. Another advantage to runtime rendering is the ability to monitor simulations as they progress, interactive rendering and simulation control. The use of MPI 1] in both codes helped facilitate their combination into a single application.
