Employer: INSA Rouen Normandie . Project: CoEC4ET – Center of Excellence in Combustion for the Energy Transition . Duration: 36 months . Start Date: Early 2027 . Advisors: Vincent Moureau, Kévin Bioche . Keywords: Reactive flows, GPU, Exascale, HPC, YALES2, OpenMP. Description of the Thesis Topic . Context: . This thesis is part of the European CoEC4ET project, a European center of excellence aimed at developing exascale simulation technologies for combustion and contributing to the energy transition. It focuses on the development of methods enabling high-performance reactive multiphysics simulations on GPU architectures. Objectives : . • Develop YALES2’sreactive multiphysics simulation capabilities on CPU-GPU architectures by integratingChemInt (BSC) forchemistry, CWIPI (ONERA) for multiphysicscoupling, and aPython/PyTorch interface. • This work will include the reduction of chemical mechanisms through clustering, in collaboration with the BSC, as well as the structuring, documentation, and profiling of software interfaces. Expected results : . New frameworks for reactive computations on GPUs, portable exascale software components and validations on European supercomputers. These activities will result in international scientific publications. Work Context . The Ph.D. student wil
