VisIt and ADIOS

  • VisIt: Large data parallel visualization tool
    • Rich set of visualization and analysis plots and operations
    • Plug-in API allows for easy extension
  • ADIOS: adaptable I/O framework
    • Provides portable, fast, scalable, easy-to-use, metadata rich output with a simple API


  • Developed a parallel XGC ADIOS reader for simulation data
  • Computation of derived turbulence quantity
  • Parallel analysis and visualization possible now on XGC simulation data

Future Directions

  • Development of feature detection and comparative analysis algorithms
  • ADIOS Visualization Schema for post processing needs
