  1. 1. Performance Analysis of GPU and CPU Parallelization on the Kmeans Algorithm

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

    Författare :Joakim Olsson; Stefan Christiansson; [2021]
    Nyckelord :;

    Sammanfattning : The K-means algorithm is one of the more known unsupervised algorithms that aims to partition data points into a specified number of clusters, where each data point belongs to the cluster with the nearest cluster center, which is also known as a centroid. However, a basic implementation of the K-means algorithm, without any optimizations, is ineffective when used in larger applications. LÄS MER

  3. 2. RISC-V Thread Isolation : Using Zephyr RTOS

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

    Författare :Gustav Midéus; Antonio Morales Chavez; [2020]
    Nyckelord :RISC-V; memory protection; embedded systems; thread isolation; real-time operating system RTOS ; IoT; RISC-V; minnesskydd; inbyggda system; trådisolering; RTOS; IoT;

    Sammanfattning : Many embedded systems lack a memory management unit (MMU) and thus often also lack protection of memory. This causes these systems to be less robust since the operating system (OS), processes, and threads are no longer isolated from each other. LÄS MER

  4. 3. Extending the Scope of Compile-time Optimizations Across Synchronization Operations

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Andreas Scherman; [2017]
    Nyckelord :;

    Sammanfattning : With the rise of multiprocessor computers, parallel computing has become a necessity in order to achieve high performance. Modern compilers are conservative in applying classical compiler optimizations to parallel programs, as the compiler might require expensive whole-code analysis in order to preserve the semantics and correctness of the code, to ensure no data races are introduced through optimizations.

  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

  7. 5. VITA 49 Radio DF : Using coherent digital receiver set with VC++ and Octave

    Kandidat-uppsats, Avdelningen för elektronikkonstruktion

    Författare :Daniel Perup; [2013]
    Nyckelord :Radio direction finding; DF; Octave; MATLAB; signal analysis; VITA 49;

    Sammanfattning : The objective of this thesis was to evaluate radio receivers that had been previously acquired for other tasks by the Swedish Defence Materiel Administration, for additional service in a radio direction finding (DF) system. The antenna, calibration signal generator and DF algorithm were provided. LÄS MER
