    • Alternative Parameters for On-The-Fly Simplification of MergeTrees 

      Werner, Kilian; Garth, Christoph (The Eurographics Association, 2020)
      Topological simplification of merge trees requires a user specified persistence threshold. As this threshold is based on prior domain knowledge and has an unpredictable relation to output size, its use faces challenges in ...

    • Approaches for In Situ Computation of Moments in a Data-Parallel Environment 

      Tsai, Karen C.; Bujack, Roxana; Geveci, Berk; Ayachit, Utkarsh; Ahrens, James (The Eurographics Association, 2020)
      Feature-driven in situ data reduction can overcome the I/O bottleneck that large simulations face in modern supercomputer architectures in a semantically meaningful way. In this work, we make use of pattern detection as a ...

    • High-Quality Rendering of Glyphs Using Hardware-Accelerated Ray Tracing 

      Zellmann, Stefan; Aumüller, Martin; Marshak, Nathan; Wald, Ingo (The Eurographics Association, 2020)
      Glyph rendering is an important scientific visualization technique for 3D, time-varying simulation data and for higherdimensional data in general. Though conceptually simple, there are several different challenges when ...

    • Improving Performance of M-to-N Processing and Data Redistribution in In Transit Analysis and Visualization 

      Loring, Burlen; Wolf, Mathew; Kress, James; Shudler, Sergei; Gu, Junmin; Rizzi, Silvio; Logan, Jeremy; Ferrier, Nicola; Bethel, E. Wes (The Eurographics Association, 2020)
      In an in transit setting, a parallel data producer, such as a numerical simulation, runs on one set of ranks M, while a data consumer, such as a parallel visualization application, runs on a different set of ranks N: One ...
