| Description | Accelerated clusters are ubiquitous, with 7 of the top 10 fastest supercomputers world wide supported by accelerators of some form (9 of the top 10 on the Green500 list). A key aspect of this technology is the fact that their computing and memory architecture differs from that of the host in which they are installed. This bachelor thesis focuses on implementing and benchmarking multiple variants of structured grid proxy apps for several dimensions in CUDA and investigating relevant performance effects. |

| Description | High performance computing is a branch of computer science that evolves very quickly, with increasingly complex architectures in both software and hardware. However, HPC application software is often developed by domain scientists, who may struggle to keep up with these innovations. Cronos is such an example, a structured grid simulation capable of computing gamma ray emissions of binary star systems. With development started over a decade ago, its programming style reflects various language standards of C++ and lacks modern features such as accelerator support or adaptive mesh refinement (AMR). The idea of AMR is to drastically reduce the computational work of a grid based simulation, by dynamically adjusting local resolution.The goal of this bachelor thesis is to provide a preliminary prototype for a new Cronos implementation that supports AMR and can be easily extended to contemporary programming models. |
