Main research findings
This research delves into the potential of Graphcore's IPU AI-optimized architecture in the realm of High-Performance Computing (HPC). Focusing on solving complex challenges like sparse systems and irregular applications, the dissertation contributes to HPC systems and application design, backed by rigorous empirical evaluation.The core objective is to evaluate the applicability of recent AI advancements to the field of HPC, with a specific focus on sparse and irregular applications. The thesis leverages empirical research, encompassing detailed experiments and analysis. This not only demonstrates how applications can seamlessly integrate with the AI accelerator but also highlights potential challenges and limitations associated with its use.In a world increasingly reliant on high-performance computing, this work's findings carry implications for both the scientific and technological communities. By bridging the gap between AI-specific architectures and HPC, the dissertation paves the way for more efficient problem-solving in diverse applications, offering insights for future advancements in this critical intersection of fields.
