The training of large language models (LLMs) requires substantial computational resources, complex software stacks, and carefully designed workflows to achieve scalability and efficiency. This report presents best practices and insights gained from the OpenGPT-X project, a German initiative focused on developing open, multilingual LLMs optimized for European languages. [...]

A modification to the setup algorithm for the multigrid preconditioner of Wilson fermions in lattice QCD is presented. A larger basis of test vectors than that used in conventional multigrid is calculated by the smoother and truncated by singular value decomposition on the chiral components of the test vectors. [...]

In der Präzisionslandwirtschaft ("Precision Farming") werden immer mehr Methoden zur effizienten und umweltverträglichen Bewirtschaftung von landwirtschaftlichen Flächen entwickelt und eingesetzt. Technische Lösungen zur schnellen Kartierung der Bodenparameter helfen dabei eine effizientere Feldbearbeitung zu ermöglichen. [...]

The challenges of designing long-term safeguards on civilian nuclear waste in underground repositories have some similarities to those of managing the monitored secure storage and disposal of nuclear weapon material recovered during weapon production processes and as part of a disarmament process. This presentation will present a model and software architecture designed for a digital twin of safeguards on civilian nuclear waste and ask how it may be adapted to be useful in a disarmament context [...]

We present a new lattice QCD calculation of the leading order hadronic vacuum polarization contribution to the muon anomalous magnetic moment $a_\mu$. We reduce uncertainties compared to our earlier computation by $40\%$, arXiv:2002.12347. [...]

Nonlinear partial differential equations frequently arise in different fields ofscience. Discretization of the nonlinear problems usually leads to large non-linear systems. [...]
