    • External Facelist Calculation with Data-Parallel Primitives 

      Lessley, Brenton; Binyahib, Roba; Maynard, Robert; Childs, Hank (The Eurographics Association, 2016)
      External facelist calculation on three-dimensional unstructured meshes is used in scientific visualization libraries to efficiently render the results of operations such as clipping, interval volumes, and material boundaries. ...

    • Megakernels Considered Harmful: Wavefront Path Tracing on GPUs 

      Laine, Samuli; Karras, Tero; Aila, Timo (ACM, 2013)
      When programming for GPUs, simply porting a large CPU program into an equally large GPU kernel is generally not a good approach. Due to SIMT execution model on GPUs, divergence in control flow carries substantial performance ...

    • Register Efficient Memory Allocator for GPUs 

      Vinkler, Marek; Vlastimil, Havran (The Eurographics Association, 2014)
      We compare four existing dynamic memory allocators optimized for GPUs and show their strengths and weaknesses. In the measurements we use three generic evaluation tests proposed in the literature and add one with a real ...

    • Ternary Sparse Matrix Representation for Volumetric Mesh Subdivision and Processing on GPUs 

      Mueller-Roemer, Johannes Sebastian; Altenhofen, Christian; Stork, André (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      In this paper, we present a novel volumetric mesh representation suited for parallel computing on modern GPU architectures. The data structure is based on a compact, ternary sparse matrix storage of boundary operators. ...

    • 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 ...
