      Biedert, Tim; Werner, Kilian; Hentschel, Bernd; Garth, Christoph (The Eurographics Association, 2017)
      An increasingly heterogeneous system landscape in modern high performance computing requires the efficient and portable adaption of performant algorithms to diverse architectures. However, classic hybrid shared-memory/distributed ...
    • Through the Concurrency Gateway: a Challenge from the Near Future of Graphics Hardware 

      Welch, P. H. (The Eurographics Association, 2004)
      The computer graphics industry, and in particular those involved with films, games and virtual reality, continue to demand more and more realistic computer generated images. The complexity of the scenes being modelled and ...
    • Time Step Prioritising in Parallel Feature Extraction on Unsteady Simulation Data 

      Wolter, M.; Hentschel, B.; Schirski, M.; Gerndt, A.; Kuhlen, T. (The Eurographics Association, 2006)
      Explorative analysis of unsteady computational fluid dynamics (CFD) simulations requires a fast extraction of flow features. For time-varying data, the extraction algorithm has to be executed for each time step in the ...
    • Time-constrained Animation Rendering on Desktop Grids 

      Aggarwal, Vibhor; Debattista, Kurt; Bashford-Rogers, Thomas; Chalmers, Alan (The Eurographics Association, 2012)
      The computationally intensive nature of high-fidelity rendering has led to a dependence on parallel infrastructures for generating animations. However, such an infrastructure is expensive thereby restricting easy access ...
    • Time-constrained High-fidelity Rendering on Local Desktop Grids 

      Aggarwal, Vibhor; Debattista, Kurt; Dubla, Piotr; Bashford-Rogers, Thomas; Chalmers, Alan (The Eurographics Association, 2009)
