      We design and implement La VALSE-a scalable visualization tool to explore tens of millions of records of reliability, availability, and serviceability (RAS) logs-for IBM Blue Gene/Q systems. Our tool is designed to meet ...

    • Interactive Visual Analysis of Multi-dimensional Metamodels 

      Gebhardt, Sascha; Pick, Sebastian; Hentschel, Bernd; Kuhlen, Torsten Wolfgang (The Eurographics Association, 2018)
      In the simulation of manufacturing processes, complex models are used to examine process properties. To save computation time, so-called metamodels serve as surrogates for the original models. Metamodels are inherently ...

    • Rapid k-d Tree Construction for Sparse Volume Data 

      Zellmann, Stefan; Schulze, Jürgen P.; Lang, Ulrich (The Eurographics Association, 2018)
      While k-d trees are known to be effective for spatial indexing of sparse 3-D volume data, full reconstruction, e.g. due to changes to the alpha transfer function during rendering, is usually a costly operation with this ...

    • Dense Texture Flow Visualization using Data-Parallel Primitives 

      Kim, Mark; Klasky, Scott; Pugmire, David (The Eurographics Association, 2018)
      Recent trends in supercomputing towards massively threaded on-node processors to increase performance has also introduced fragmented software support. In response to this changing landscape, new scientific visualization ...

    • Revisiting the Evaluation of In Situ Lagrangian Analysis 

      Sane, Sudhanshu; Bujack, Roxana; Childs, Hank (The Eurographics Association, 2018)
      In situ usage of Lagrangian techniques has proven to be superior with respect to emerging supercomputing trends than the traditional Eulerian approach for scientific flow analysis. However, previous studies have not informed ...

    • Performance-Portable Particle Advection with VTK-m 

      Pugmire, David; Yenpure, Abhishek; Kim, Mark; Kress, James; Maynard, Robert; Childs, Hank; Hentschel, Bernd (The Eurographics Association, 2018)
      Particle advection is the fundamental kernel behind most vector field visualization methods. Yet, the efficient parallel computation of large amounts of particle traces remains challenging. This is exacerbated by the variety ...
