  1. 1. Vectorization of the Jacobi method with single- and multiple right-hand sides

    University essay from Lunds universitet/Matematikcentrum; Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Patrik Paaso; [2022]
    Keywords : C ; Vectorization; SIMD; DUNE; VCL; Vc; Jacobi method; Jacobi iteration; discrete Poisson s equation; Stationary iterative methods; Computational science; Optimization; Numerical analysis; Mathematics and Statistics;

    Abstract : Vectorization has been an important consideration for scientific com- puting performance for a long time. Early super computers were designed around vectorization, the so called ”vector computers”, but recent trends point toward favouring other computer architectures, and vector comput- ers are much more rare than they used to be.

  3. 2. Deep Learning for Dynamic Portfolio Optimization

    University essay from KTH/Matematisk statistik

    Author : Victor Molnö; [2021]
    Keywords : Dynamic portfolio optimization; No-trade-region; Deep learning; Policy iteration; Dynamisk portföljoptimering; Handelsstoppregion; Djupinlärning; Policyiterering;

    Abstract : This thesis considers a deep learning approach to a dynamic portfolio optimization problem. A proposed deep learning algorithm is tested on a simplified version of the problem with promising results, which suggest continued testing of the algorithm, on a larger scale for the original problem.

  4. 3. Partitioned Multirate Time Integration for Coupled Systems of Ordinary Differential Equations

    University essay from Lunds universitet/Matematik LTH

    Author : Joost Kranenborg; [2018]
    Keywords : Waveform iteration; waveform relaxation; multirate time integration; parallel computing; Mathematics and Statistics;

    Abstract : In this thesis a new method for the numerical solution of coupled systems of ordinary differential equations is investigated. To understand this new method, the workings of existing Waveform iteration methods, in particular the Jacobi and Gauß-Seidel methods were explored first. READ MORE

  5. 4. Comparison of Shared memory based parallel programming models

    University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Author : Srikar Chowdary Ravela; [2010]
    Keywords : Parallel Programming models; Distributed memory; Shared memory; Dwarfs; Development time; Speedup; Data parallelism; Dense Matrix dwarfs; threading models; Tasking models; Directive models.;

    Abstract : Parallel programming models are quite challenging and emerging topic in the parallel computing era. These models allow a developer to port a sequential application on to a platform with more number of processors so that the problem or application can be solved easily. READ MORE
