Thomas worked on the TUM-DSE/doctor-cluster-config repository, focusing on infrastructure management and system configuration using Nix. Over two months, he stabilized the jamie host by removing GPU-specific customizations, ensuring alignment with the cluster’s baseline configuration and preventing unintended module deployment. He then introduced hardware-assisted virtualization by enabling explicit IOMMU support, developing a dedicated AMD IOMMU Nix module and integrating it into the configuration system. This work improved VM passthrough capabilities and resource isolation for virtualized workloads. Thomas’s contributions addressed both configuration drift and virtualization requirements, demonstrating depth in infrastructure automation and virtualization with a focus on reproducibility and maintainability.
