1. Relaxed Priority Queue & Evaluation of Locks
University essay from Göteborgs universitet/Institutionen för data- och informationsteknikAbstract : We present a new, lock-free and concurrent priority queue, utilizing some ideas from [1] by Rukundo et al., that relaxes the traditional sequential semantics of the delete_min operation to achieve better scalability and performance.

2. Thread Scheduling for Hardware Stress Testing on Bare-metal Devices
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : Testing a compiler is an important, but complicated task, especially when compiling and running concurrent programs using C11 atomic operations. This thesis is dedicated to developing a compiler tester for the atomic operations and memory models introduced in the C11 standard. READ MORE

3. Quantum Computing in Nuclear Physics
University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenAbstract : In this thesis, we investigate many–body systems using simulations of quan- tum computers. Quantum computing is a computational paradigm based on qubits which are defined in a Hilbert space instead of the familiar binary bits. READ MORE

4. Compiler Testing of C11 Atomics for Arm and RISC-V
University essay from Uppsala universitet/DatorteknikAbstract : 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.

5. Towards an Efficient Spectral Element Solver for Poisson’s Equation on Heterogeneous Platforms
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)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
