1. Using GPU-aware message passing to accelerate high-fidelity fluid simulations
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : 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. READ MORE

2. 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
