Gauss Fusion, a European initiative developing a stellarator-based fusion power plant, extensively uses simulation to support reactor design and optimisation. This involves running specialised codes such as STELLOPT and SIMSOPT to evaluate plasma behaviour and reactor geometry. To support these workloads, the company uses Qarnot’s distributed HPC platform, where computations are executed across decentralised nodes instead of conventional data centres. This enables large-scale parallel studies required for iterative design. The platform also reuses heat generated during computation, connecting intensive simulation workloads with energy efficiency considerations in fusion system development.
