    • Cross-Segment Load Balancing in Parallel Rendering 

      Erol, Fatih; Eilemann, Stefan; Pajarola, Renato (The Eurographics Association, 2011)
      With faster graphics hardware comes the possibility to realize even more complicated applications that require more detailed data and provide better presentation. The processors keep being challenged with bigger amount of ...

    • Data-Parallel Mesh Connected Components Labeling and Analysis 

      Harrison, Cyrus; Childs, Hank; Gaither, Kelly P. (The Eurographics Association, 2011)
      We present a data-parallel algorithm for identifying and labeling the connected sub-meshes within a domaindecomposed 3D mesh. The identification task is challenging in a distributed-memory parallel setting because connectivity ...

    • Distributed OpenGL Rendering in Network Bandwidth Constrained Environments 

      Neal, Braden; Hunkin, Paul; McGregor, Antony (The Eurographics Association, 2011)
      Display walls made from multiple monitors are often used when very high resolution images are required. To utilise a display wall, rendering information must be sent to each computer that the monitors are connect to. The ...

    • Efficient I/O for Parallel Visualization 

      Fogal, Thomas; Krüger, Jens (The Eurographics Association, 2011)
      While additional cores and newer architectures, such as those provided by GPU clusters, steadily increase available compute power, memory and disk access has not kept pace, and most believe this trend will continue. It is ...

    • GPU Algorithms for Diamond-based Multiresolution Terrain Processing 

      Yalçin, M. Adil; Weiss, Kenneth; Floriani, Leila De (The Eurographics Association, 2011)
      We present parallel algorithms for processing, extracting and rendering adaptively sampled regular terrain datasets represented as a multiresolution model defined by a super-square-based diamond hierarchy. This model ...

    • Interactive Particle Tracing in Time-Varying Tetrahedral Grids 

      Bußler, Michael; Rick, Tobias; Kelle-Emden, Andreas; Hentschel, Bernd; Kuhlen, Torsten (The Eurographics Association, 2011)
      Particle tracing methods are a fundamental class of techniques for vector field visualization. Specifically, interactive particle advection allows the user to rapidly gain an intuitive understanding of flow structures. ...

    • Load Balancing Utilizing Data Redundancy in Distributed Volume Rendering 

      Frey, Steffen; Ertl, Thomas (The Eurographics Association, 2011)
      In interactive volume rendering, the cost for rendering a certain block of the volume strongly varies with dynamically changing parameters (most notably the camera position and orientation). In distributed environments ...

    • Optimal Multi-Image Processing Streaming Framework on Parallel Heterogeneous Systems 

      Ha, Linh K.; Krüger, Jens; Comba, Joao; Joshi, Sarang; Silva, Cláudio T. (The Eurographics Association, 2011)
      Atlas construction is an important technique in medical image analysis that plays a central role in understanding the variability of brain anatomy. The construction often requires applying image processing operations to ...

    • Parallel Computational Steering and Analysis for HPC Applications using a ParaView Interface and the HDF5 DSM Virtual File Driver 

      Biddiscombe, John; Soumagne, Jerome; Oger, Guillaume; Guibert, David; Piccinali, Jean-Guillaume (The Eurographics Association, 2011)
      We present a framework for interfacing an arbitrary HPC simulation code with an interactive ParaView session using the HDF5 parallel IO library as the API. The implementation allows a flexible combination of parallel ...

    • Parallel Gradient Domain Processing of Massive Images 

      Philip, Sujin; Summa, Brian; Bremer, Peer-Timo; Pascucci, Valerio (The Eurographics Association, 2011)
      Gradient domain processing remains a particularly computationally expensive technique even for relatively small images. When images become massive in size, giga or terapixel, these problems become particularly troublesome ...

    • Parallel In Situ Coupling of Simulation with a Fully Featured Visualization System 

      Whitlock, Brad; Favre, Jean M.; Meredith, Jeremy S. (The Eurographics Association, 2011)
      There is a widening gap between compute performance and the ability to store computation results. Complex scientific codes are the most affected since they must save massive files containing meshes and fields for offline ...

    • A Preview and Exploratory Technique for Large-Scale Scientific Simulations 

      Tikhonova, Anna; Yu, Hongfeng; Correa, Carlos D.; Chen, Jacqueline H.; Ma, Kwan-Liu (The Eurographics Association, 2011)
      Successful in-situ and remote visualization solutions must have minimal storage requirements and account for only a small percentage of supercomputing time. One solution that meets these requirements is to store a compact ...

    • Real-Time Ray Tracer for Visualizing Massive Models on a Cluster 

      Ize, Thiago; Brownlee, Carson; Hansen, Charles D. (The Eurographics Association, 2011)
      We present a state of the art read-only distributed shared memory (DSM) ray tracer capable of fully utilizing modern cluster hardware to render massive out-of-core polygonal models at real-time frame rates. Achieving this ...

    • Revisiting Parallel Rendering for Shared Memory Machines 

      Nouanesengsy, Boonthanome; Ahrens, James; Woodring, Jonathan; Shen, Han-Wei (The Eurographics Association, 2011)
      Increasing the core count of CPUs to increase computational performance has been a significant trend for the better part of a decade. This has led to an unprecedented availability of large shared memory machines. Programming ...
