  1. 1. Development of Stockham Fast Fourier Transform using Data-Centric Parallel Programming

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

    Author : Gabriel Bengtsson; [2020]
    Keywords : ;

    Abstract : Writing efficient scientific applications for modern High Performance Computing (HPC) systems has become much harder during the last years due to the rise of heterogeneous computer architectures. The inclusion of hardware accelerators has caused an increase in the number of required technologies to reach high performance, a change that has programming these systems outside the skill-set of a domain scientist.

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

    Author : Andreas Heiskanen; Erik Johansson; [2018]
    Keywords : fftw; discrete fourier transform; fast fourier transform; hpc; perf; cache; memory analysis;

    Abstract : Discrete Fourier Transforms (DFTs) are used in a wide variety of dif-ferent scientific areas. In addition, there is an ever increasing demand on fast and effective ways of computing DFT problems with large data sets. The FFTW library is one of the most common used libraries when computing DFTs. READ MORE
