  1. 1. Towards an Efficient Spectral Element Solver for Poisson’s Equation on Heterogeneous Platforms

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jonas Nylund; [2022]
    Nyckelord :Neko; CUDA; Heterogeneous hardware; GPU; Gather-Scatter; HPC; CFD; Neko; CUDA; Heterogena plattformar; GPU; Gather-Scatter; Högprestandabe-räkningar; Beräkningsströmningsdynamik;

    Sammanfattning : Neko is a project at KTH to refactor the widely used fluid dynamics solver Nek5000 to support modern hardware. Many aspects of the solver need adapting for use on GPUs, and one such part is the main communication kernel, the Gather-Scatter (GS) routine. To avoid race conditions in the kernel, atomic operations are used, which can be inefficient. LÄS MER

  3. 2. On Embarrassingly Parallel Max- Min Ant Colony Optimization for Traveling Salesperson Problem

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Mohamed Mohsin; Ajanth Thangavelu; [2021]
    Nyckelord :;

    Sammanfattning : Ant Colony Optimization (ACO) is a technique which can be used to find approximate Hamilton cycles for the Traveling Salesperson Problem (TSP). OpenMP is a framework which suites well for building multithreaded applications. LÄS MER

  4. 3. Parallellisering av Sliding Extensive Cancellation Algorithm (ECA-S) för passiv radar med OpenMP

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Andreas Johansson Hultberg; [2021]
    Nyckelord :Extensive Cancellation Algorithm ECA ; ECA-S; Passive Radar; Optimization; OpenMP; Parallel Processing; Shared Memory Model; Central Processing Unit CPU ;

    Sammanfattning : Software parallelization has gained increasing interest since the transistor manufacturing of smaller chips within an integrated circuit has begun to stagnate. This has led to the development of new processing units with an increasing number of cores. LÄS MER

  5. 4. Improving the performance of GPU-accelerated spatial joins

    Kandidat-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Dusan Viktor Hrstic; [2017]
    Nyckelord :GPU-acceleration; spatial joins; threads optimizations; warp scheduling; GPU-acceleration; rumsliga föreningar; optimering av trådar; warp schedulering;

    Sammanfattning : Data collisions have been widely studied by various fields of science and industry. Combing CPU and GPU for processing spatial joins has been broadly accepted due to the increased speed of computations. LÄS MER
