Summary
👤
Senior🎓
Top SchoolLouis Poirel is an HPC Benchmarks Engineer with a PhD in scientific computing and nine years’ experience accelerating large-scale simulations at the intersection of applied research and industrial software. Trained at École Polytechnique and ENSEEIHT, he moved from environmental hydraulics to high-performance numerical methods, authoring a thesis on domain-decomposition preconditioners for hybrid heterogeneous parallel solvers at Inria. He modernized a multiphysics C++ finite-element solver at Michelin to improve parallel efficiency and now applies that expertise at Eviden/Bull on industrial HPC projects and benchmarks. An active contributor to the Spack ecosystem—particularly the petsc package—he bridges build-system integration, dependency resolution and performance-aware packaging for widely used scientific libraries. Based in Rennes, he combines deep numerical modeling know-how with practical software engineering, often spotting cross-layer performance wins that are not obvious from code alone.
