    • Packet-Oriented Streamline Tracing on Modern SIMD Architectures 

      Hentschel, Bernd; Göbbert, Jens Henrik; Klemm, Michael; Springer, Paul; Schnorr, Andrea; Kuhlen, Torsten W. (The Eurographics Association, 2015)
      The advection of integral lines is an important computational kernel in vector field visualization. We investigate how this kernel can profit from vector (SIMD) extensions in modern CPUs. As a baseline, we formulate a ...

    • SIMD Parallel Ray Tracing of Homogeneous Polyhedral Grids 

      Rathke, Brad; Wald, Ingo; Chiu, Kenneth; Brownlee, Carson (The Eurographics Association, 2015)
      Efficient visualization of unstructured data is vital for domain scientists, yet is often impeded by techniques which rely on intermediate representations that consume time and memory, require resampling data, or inefficient ...

    • TOD-Tree: Task-Overlapped Direct send Tree Image Compositing for Hybrid MPI Parallelism 

      Grosset, A. V. Pascal; Prasad, Manasa; Christensen, Cameron; Knoll, Aaron; Hansen, Charles (The Eurographics Association, 2015)
      Modern supercomputers have very powerful multi-core CPUs. The programming model on these supercomputer is switching from pure MPI to MPI for inter-node communication, and shared memory and threads for intra-node communication. ...

    • Visualization of 2DWave Propagation by Huygens' Principle 

      Heßel, Stefan; Fernandes, Oliver; Boblest, Sebastian; Offenhäuser, Philipp; Hoffmann, Malte; Beck, Andrea; Ertl, Thomas; Glass, Colin; Munz, Claus-Dieter; Sadlo, Filip (The Eurographics Association, 2015)
      We present a novel technique to visualize wave propagation in 2D scalar fields. Direct visualization of wave fronts is susceptible to visual clutter and interpretation difficulties due to space-time interference and global ...

    • Visualization of High-Resolution Weather Model Data 

      Liu, Si; Foss, Greg; Abram, Greg; Bowen, Anne (The Eurographics Association, 2015)
      Significant bottlenecks from I/O required novel techniques be used for a high-resolution severe weather simulation and visualization in the region centered around O'Hare International Airport. The Raytheon Company collaborated ...

    • Visualization Showcase: General-Relativistic Black Hole Visualization 

      Müller, Thomas; Boblest, Sebastian; Weiskopf, Daniel (The Eurographics Association, 2015)
      Black holes are among the most fascinating and weird objects in the universe. They distort space and time in their close neighborhood in a way that is far beyond our every day experience. We demonstrate the visual effects ...

    • Visualizing Groundwater Flow Through Karst Limestone 

      Knoll, Aaron; Brownlee, Carson; Navrátil, Paul; Cunningham, Kevin J.; Sukop, Michael C.; Garcia, Sadé (The Eurographics Association, 2015)
      Water management is critical in Florida where freshwater is often rare or, in times of flooding, overabundant and seawater frequently contaminates available sources. Professor Michael Sukop from Florida International ...

    • Volume Rendering Via Data-Parallel Primitives 

      Larsen, Matthew; Labasan, Stephanie; Navrátil, Paul; Meredith, Jeremy; Childs, Hank (The Eurographics Association, 2015)
      Supercomputing designs have recently evolved to include architectures beyond the standard CPU. In response, visualization software must be developed in a manner that obviates the need for porting all visualization algorithms ...
