VisIt and PIConGPU

  • VisIt: Large data parallel visualization tool
    • Rich set of visualization and analysis plots and operations
    • Plug-in API allows for easy extension
  • PIConGPU: Particle code running on Titan
    • Simulation of hundreds of billions of particles on 18,000 nodes of Titan

Result/Impact

Developed a VisIt data reader for the field data in the simulation.
Developed particle rendering techniques to look at selected particles for analysis
Aided in analysis for Gordon Bell prize finalist project, and several presentations and publications
