An Interactive Remote Visualization Environment for an
Electromagnetic Scattering Simulation on a High
Performance Computing System 

SUMMARY 
   Electromagnetic scattering (EMS) simulation is an important computationally intensive application within
   the field of electromagnetics. Advances in high performance computing and communication (HPCC) and
   data visualization environments (DVE) provide new opportunities to visualize real-time simulation
   problems such as EMS that require significant computational resources. 

   In this work, an integrated interactive visualization environment was created for an EMS simulation,
   coupling a graphical user interface (GUI) for runtime simulation parameter input and 3D 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 a simulation of electromagnetic scattering from a plane conducting two slots as a case study in this
   work, we explore the AVS data flow methodology to naturally integrate data visualization, parallel
   systems and heterogeneous computing. Major issues in integrating this remote visualization system are
   investigated, including task decomposition, system integration, concurrent control, and a high level
   DVE-based distributed programming model.
