Summary
👤
Senior🎓
Top SchoolPierre Kestener is a Software Research Engineer with 11+ years of experience specializing in high-performance computing and embedded systems, focused on porting and optimizing numerical simulation codes (CFD, DFT, LBM) for large GPU and multicore clusters. He combines deep GPU programming expertise (CUDA, OpenCL, SYCL, Kokkos/C++) with MPI/OpenMP parallelism and pragmatic build-system work, having contributed to notable projects like Kokkos and RamsesGPU. At CEA he leads refactoring efforts to make scientific solvers architecture- and performance-portable, and also brings experience in real-time embedded software for space missions. An educator and trainer, he teaches GPU programming and PINNs and maintains open-source tooling (xsmurf, CanoP) linking research, reproducibility, and production HPC. Notably, his background in image processing and a PhD in electrical engineering underpin a rare blend of algorithmic insight and low-level systems craftsmanship.
