    • Fault-tolerance for MPI Codes on Computational Clusters 

      Hagen, Knut Imar (Master thesis, 2007)
      This thesis focuses on fault-tolerance for MPI codes on computational clusters. When an application runs on a very large cluster with thousands of processors, there is likely that a process crashes due to a hardware or ...

    • FDTD on Distributed Heterogeneous Multi-GPU Systems 

      Myklebost, Eirik (Master thesis, 2014)
      Finite-Difference Time-Domain (FDTD) is a popular technique for modeling computational electrodynamics, and is used within many research areas, such as the development of antennas, ultrasound imaging, and seismic wave ...

    • Framework for Polygonal Structures Computations on Clusters 

      Larsen, Leif Christian (Master thesis, 2007)
      Seismological applications use a 3D grid to represent the subsea rock structure. Many computations, such as detecting layers of rock in the seismic, can be done using the 3D grid exclusively. However, some algorithms for ...

    • Framework for Real-Time Editing of Endless Procedural Terrains 

      Helsing, Johan Klokkhammer (Master thesis, 2014)
      Procedural content generation is the act of creating video game content automatically, through algorithmic means. In online procedural generation, content is generated as the game is running on the consumer's computer. Online ...
