  1. 1. Compiler Testing of C11 Atomics for Arm and RISC-V

    University essay from Uppsala universitet/Datorteknik

    Author : Hampus Adolfsson; [2022]
    Keywords : compiler; compiler testing; atomics; c11 atomics; arm; risc-v;

    Abstract : The C11 standard introduced atomic types and operations, with an accompanying memory model, to enable the use of shared variables in concurrent programs. In this thesis, I demonstrate how compilers can be tested, in a way that is deterministic and covers the entire set of atomic operations, to ensure they correctly implement C11 atomics and the C11 memory model.

  3. 2. Towards an Efficient Spectral Element Solver for Poisson’s Equation on Heterogeneous Platforms

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

    Author : Jonas Nylund; [2022]
    Keywords : Neko; CUDA; Heterogeneous hardware; GPU; Gather-Scatter; HPC; CFD; Neko; CUDA; Heterogena plattformar; GPU; Gather-Scatter; Högprestandabe-räkningar; Beräkningsströmningsdynamik;

    Abstract : Neko is a project at KTH to refactor the widely used fluid dynamics solver Nek5000 to support modern hardware. Many aspects of the solver need adapting for use on GPUs, and one such part is the main communication kernel, the Gather-Scatter (GS) routine. To avoid race conditions in the kernel, atomic operations are used, which can be inefficient. READ MORE

  4. 3. Validating results from the Molten Salt Reactor Experiment by use of turbulent CFD simulations : A study of a modified U-tube shell-and-tube primary heat exchanger and radiator with molten salts

    Abstract : Background Nuclear reactors utilizing molten fuels rather than solid fuels show a massive advantage in energy yield, waste handling and safety features. The only successful reactor utilizing a molten fuel was called the ‘Molten Salt Reactor Experiment’ (MSRE), built and operated in the Oak Ridge national laboratory (ORNL) in Tennessee, U.S.A.
