  1. 6. Using GPU-aware message passing to accelerate high-fidelity fluid simulations

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

    Författare :Jacob Wahlgren; [2022]
    Nyckelord :high-performance computing; computational fluid dynamics; spectral element method; graphical processing units; message passing interface; högprestandaberäkningar; beräkningsströmningsdynamik; spektralelementmetoden; grafikprocessorer; meddelandeförmedlingsgränssnitt;

    Sammanfattning : Motivated by the end of Moore’s law, graphics processing units (GPUs) are replacing general-purpose processors as the main source of computational power in emerging supercomputing architectures. A challenge in systems with GPU accelerators is the cost of transferring data between the host memory and the GPU device memory. LÄS MER

  3. 7. Constraint based network communications in a virtual environment of a proprietary hardware

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Saaish Bhonagiri; Soumith Kumar Mudugonda; [2022]
    Nyckelord :Network communication; SR-IOV; OVS DPDK; MPI; OpenStack; Kubernetes;

    Sammanfattning : The specialized hardware remains a key component of the mobile networks, but at the same time, the telecom industry is adapting a vision of a fully programable distributed end-to-end network with cloud style management and Software-Defined Networking. In the specialized hardware programmable network, it will be possible to place workloads across abstracted compute and networking infrastructure. LÄS MER

  4. 8. Parallelisation methods applied to a finite element code

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Marc Pierre; [2022]
    Nyckelord :FEM; parallelism; superelement; schur s complement; FEM; parallellitet; superelement; Schurs komplement;

    Sammanfattning : With Moore’s Law being verified, all we had to do was wait a few years to get more computing power. However, this increase in power is no longer exclusively based on the performance of the processor, but more and more on its ability to execute several tasks simultaneously. LÄS MER

  5. 9. Integrating SkePU's algorithmic skeletons with GPI on a cluster

    Master-uppsats, Linköpings universitet/Programvara och system

    Författare :Joel Almqvist; [2022]
    Nyckelord :SlePU; cluster; GPI; MPI; OpenMP; parallel programming; HPC; algorithmic skeletons; distributed computing; SkePU; kluster; GPI; MPI; OpenMP; parallellprogrammering; HPC; algoritmiska skelett;

    Sammanfattning : As processors' clock-speed flattened out in the early 2000s, multi-core processors became more prevalent and so did parallel programming. However this programming paradigm introduces additional complexities, and to combat this, the SkePU framework was created. LÄS MER

  7. 10. Hardware Architecture Impact on Manycore Programming Model

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Erik Stubbfält; [2021]
    Nyckelord :Computer Architecture; Parallel Computing;

    Sammanfattning : This work investigates how certain processor architectures can affectthe implementation and performance of a parallel programming model.The Ericsson Many-Core Architecture (EMCA) is compared and contrastedto general-purpose multicore processors, highlighting differencesin their memory systems and processor cores.
