      Biedert, Tim; Garth, Christoph (The Eurographics Association, 2015)
      High-fidelity simulation models on large-scale parallel computer systems can produce data at high computational throughput, but modern architectural trade-offs make full persistent storage to the slow I/O subsystem ...
    • Cross-Node Occlusion in Sort-Last Volume Rendering 

      Marchesin, Stéphane; Ma, Kwan-Liu (The Eurographics Association, 2010)
      In the field of parallel volume rendering, occlusion is a concept which is already widely exploited in order to improve performance. However, when one moves to larger datasets the use of parallelism becomes a necessity, ...
