1. Validation of a moderate Reynolds number channel in Neko
Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : Neko is a portable framework for high-order spectral element flow simulations[1]. Originally from Nek5000, Neko not only inherited its numerical stability and well-performance, but also added the benefits of dynamic memory and support for many current accelerator backends. LÄS MER
2. Using GPU-aware message passing to accelerate high-fidelity fluid simulations
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)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. Towards an Efficient Spectral Element Solver for Poisson’s Equation on Heterogeneous Platforms
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
