    • Dynamic I/O Budget Reallocation For In Situ Wavelet Compression 

      Marsaglia, Nicole J.; Li, Shaomeng; Belcher, Kristi; Larsen, Matthew; Childs, Hank (The Eurographics Association, 2019)
      In situ wavelet compression is a potential solution for enabling post hoc visualization on supercomputers with slow I/O systems. While this in situ compression is typically accomplished by allocating an equal storage budget ...
    • HyLiPoD: Parallel Particle Advection Via a Hybrid of Lifeline Scheduling and Parallelization-Over-Data 

      Binyahib, Roba; Pugmire, David; Childs, Hank (The Eurographics Association, 2021)
      Performance characteristics of parallel particle advection algorithms can vary greatly based on workload.With this short paper, we build a new algorithm based on results from a previous bake-off study which evaluated the ...
    • An Interpolation Scheme for VDVP Lagrangian Basis Flows 

      Sane, Sudhanshu; Childs, Hank; Bujack, Roxana (The Eurographics Association, 2019)
      Using the Eulerian paradigm, accurate flow visualization of 3D time-varying data requires a high temporal resolution resulting in large storage requirements. The Lagrangian paradigm has proven to be a viable in situ-based ...
    • Machine Learning-Based Autotuning for Parallel Particle Advection 

      Schwartz, Samuel D.; Childs, Hank; Pugmire, David (The Eurographics Association, 2021)
      Data-parallel particle advection algorithms contain multiple controls that affect their execution characteristics and performance, in particular how often to communicate and how much work to perform between communications. ...
    • PGV 2019: Frontmatter 

      Childs, Hank; Frey, Steffen (The Eurographics Association, 2019)
    • Scalable In Situ Computation of Lagrangian Representations via Local Flow Maps 

      Sane, Sudhanshu; Yenpure, Abhishek; Bujack, Roxana; Larsen, Matthew; Moreland, Kenneth; Garth, Christoph; Johnson, Chris R.; Childs, Hank (The Eurographics Association, 2021)
      In situ computation of Lagrangian flow maps to enable post hoc time-varying vector field analysis has recently become an active area of research. However, the current literature is largely limited to theoretical settings ...
