An interactive remote visualization environment for an electromagnetic scattering simulation on a high performance computing system

An integrated interactive visualization environment was created for an electromagnetic scattering (EMS) simulation, coupling a graphical user interface (GUI) for runtime simulation parameters input and 3-D rendering output on a graphical workstation, with computational modules running on a parallel supercomputer and two workstations. Application Visualization System (AVS) was used as integrating software to facilitate both networking and scientific data visualization. Using the EMS simulation as a case study, the authors explore the AVS dataflow methodology to naturally integrate data visualization, parallel systems and heterogeneous computing. Major issues in integrating this remote visualization system are discussed, including task decomposition, system integration, concurrent control, and a high level data-visualization-environment distributed programming model.
