  1. 1. Design and evaluation of a plain MPI-based cluster execution backend for the SkePU 3 skeleton programming framework

    University essay from Linköpings universitet/Programvara och system

    Author : Alexander Zeijlon; [2023]
    Keywords : SkePU; skeleton programming; algorithmic skeletons; HPC; cluster; parallel programming; MPI; OpenMP; CUDA; Hybrid; NUMA;

    Abstract : SkePU 3 is a framework for parallel program execution that uses higher order functions called skeletons, which provide a layer of abstraction between user code and the parallel implementation it provides through its backends. The backend that enables SkePU to run on an HPC cluster has a slowdown of a factor two. READ MORE

  3. 2. Using MPI One-Sided Communication for Parallel Sudoku Solving

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Henrik Aili; [2023]
    Keywords : exact cover; sudoku; parallelization; MPI;

    Abstract : This thesis investigates the scalability of parallel Sudoku solving using Donald Knuth’s Dancing Links and Algorithm X with two different MPI communication methods: MPI One-Sided Communication and MPI Send-Receive. The study compares the performance of the two communication approaches and finds that MPI One-Sided Communication exhibits better scalability in terms of speedup and efficiency. READ MORE

  4. 3. Individual Layer Scaling and Redundancy Reduction of Singleshot Multiplane Images for View Synthesis

    University essay from Lunds universitet/Matematik LTH

    Author : Max Bergfelt; [2023]
    Keywords : MPI; multiplane images; view synthesis; rendering; computer vision; unity; Mathematics and Statistics;

    Abstract : Image-based rendering for view synthesis is a field within computer vision that has seen a growing number of research activity within the past few years, much due to deep learning techniques emerging, allowing researchers to re-format view synthesis as a learning problem. The multiplane image (MPI) is a recently proposed learning-based layered 3D representation, created from one or a few input images for the purpose of rendering novel views. READ MORE

  5. 4. Modelling the effect of multimodal pain rehabilitation

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Rode Grönkvist; [2022-09-21]
    Keywords : ;

    Abstract : Chronic pain is a cause of suffering in a large share of the population and a leading public health problem. Multimodal pain rehabilitation (MMR) is a multidisciplinary rehabilitation method commonly used to treat chronic pain. In Sweden, MMR providers contribute patient data to a national registry (the SQRP). READ MORE

  6. 5. Using GPU-aware message passing to accelerate high-fidelity fluid simulations

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jacob Wahlgren; [2022]
    Keywords : high-performance computing; computational fluid dynamics; spectral element method; graphical processing units; message passing interface; högprestandaberäkningar; beräkningsströmningsdynamik; spektralelementmetoden; grafikprocessorer; meddelandeförmedlingsgränssnitt;

    Abstract : Motivated by the end of Moore’s law, graphics processing units (GPUs) are replacing general-purpose processors as the main source of computational power in emerging supercomputing architectures. A challenge in systems with GPU accelerators is the cost of transferring data between the host memory and the GPU device memory. READ MORE
