Biography
My name is Thibault Cimic, I’m a research engineer in applied Mathematics specialized in linear algebra and PDE solvers. My job consist of getting maths ideas into computers.
I’m currently working at the CEA/L_Sim laboratory in Grenoble since May 2025. My job there consist mainly of porting the psolver module of the BigDFT suite to the performance portability programming ecosystem Kokkos developped at the CEA/Saclay.
My previous position was at CEA/Saclay (ending in August 2024) as a HPC research engineer at Laboratoire Genie Logiciel, where I’ve distributed a high order spectral finite element code called Ondo for wave propagation modelisation on distrubuted memory architecture.
Before that I’ve been working in the ALPINES team at INRIA in Paris, France, lead by Laura Grigori. It’s a team both conjoint with INRIA (INRIA’s website here) and Laboratoire Jacques Louis Lions (LJLL) of the Sorbonne Université, science division (LJLL’s website here). There, I have developped 2-lvl precondionning techniques for an astrophysic problem called the map-making problem for the cosmic microwave background (CMB for short), you can find more details about that on my dedicated page : B3DCMB.
