  1. 1. Analysis and optimization of an implementation of hierarchical Tucker tensors

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Daniel Wallgren; [2023]
    Nyckelord :;

    Sammanfattning : The hierarchical Tucker tensor format is a format for approximated tensors which has been decomposed into smaller parts. This structure can be useful in high-dimensional computer simulations. One implementation of this structure is in a library called htlib. LÄS MER

  3. 2. Efficiently Solving the Exact Cover Problem in OpenMP

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Leo Hall; [2023]
    Nyckelord :Exact Cover; openmp; parallelization;

    Sammanfattning : The exact cover problem is an NP-complete problem with many widespread use cases such as crew scheduling, railway scheduling, benchmarking as well as having applications in set theory. Existing algorithms can be slow when dealing with large datasets however. LÄS MER

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

    Master-uppsats, Linköpings universitet/Programvara och system

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

    Sammanfattning : 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. LÄS MER

  5. 4. Parallel Kafka Producer Applications : Their performance and its limitations

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Arvid Sundbom; [2023]
    Nyckelord :Distriubted Systems; Parallel Systems; Apache Kafka; Rust; OpenMP;

    Sammanfattning : "This paper examines multi-threaded Kafka producer applications, and how the performance of such applications is affected by how the number of producer instances relates to the number of executing threads. Specifically, the performance of such applications when using a single producer instance, shared among all threads, and when each thread is allotted a separate, private instance, is compared.

  7. 5. Convection in a spherical shell under rapid rotation: numerical simulations

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Camille Rambert; [2022]
    Nyckelord :convection; rapid rotation; spectral methods; spherical geometry;

    Sammanfattning : A numerical method for solving the buoyancy-driven magneto-convection equations in a rapidly rotating spherical shell is presented. The method is implemented through a FORTRAN 90 program, based on a FORTRAN 66 code written by Hollerbach [International Journal for Numerical Methods in Fluids, 32 (2000)] and partially translated in FORTRAN 90 by Riquier.
