Benoît Martin is a Research Scientist at Maison de la Simulation, a research laboratory affiliated with CEA, CNRS,
Université Paris-Saclay, and Université Versailles Saint-Quentin. He earned his PhD in distributed systems from
Sorbonne Université in Paris, under the supervision of Marc Shapiro. His academic background includes a BSc and an
Engineering degree from École Supérieure de Génie Informatique (ESGI) in 2012 and 2015, respectively, as well as
an MSc from Université du Québec à Chicoutimi (UQAC) in 2015. Before pursuing his PhD, he worked as an engineer in
high-performance computing and the fintech industry, and as a research engineer at Inria with the Aramis team.
His current research focuses on in-situ analytics in high-performance computing, particularly addressing challenges
related to distributed systems and programming models. His interests include Transactional Memory Models,
Consistency Models for Shared Memory, Conflict-Free Replicated Data Types (CRDTs), and the Actor Model.
Jacques Morice, PhD. CEA/MdlS
Jacques Morice is a Research Engineer at Maison de la Simulation, a collaborative laboratory involving CEA, CNRS, Université Paris-Saclay,
and Université Versailles Saint-Quentin. He joined the PDI team in October 2024 in the goal of developing software to
bridge between physical simulation, data analysis, and IA in the context of high-performance computing.
Jacques obtained a PhD in applied mathematics and scientific computing from the University of Bordeaux I.
Before joining the PDI team, he worked on software development for physical applications (for example FreeFEM).
Julian Auriac. CEA/MdlS
Julian Auriac is Research Engineer in computer science, HPC & AI, currently working at the Maison de la Simulation (MdlS),
a french collaborative laboratory involving CEA, CNRS, and UVSQ. He is the latest addition to the PDI team,
where his work focuses on PDI core and the DEISA plugin through the lenses of high-performance computing
and parallel software engineering. After his engineering school, Julian specialized in HPC & AI through a
specialized master’s course.
Julien Bigot is a permanent CEA computer scientist at Maison de la Simulation where he leads the Science of Computing team.
His research focuses on programming models for high-performance computing. He is especially interested in the
question of separation of concerns between the simulated domain specific aspects and optimization aspects.
He aims to concretize his research into production-level software like the DDC, Deisa, or PDI libraries
whose development he started himself, or Kokkos, a project of the Linux Foundation originating from the US DoE.
He also aims to apply these libraries in production into real codes like the Gysela code for example.
He leads the CExA project that contributes to the Kokkos ecosystem, and in NumPEx, that intends to build the
software stack for the French Exascale machines. He co-leads the Exa-DoST work on I/O and data analysis libraries and tools.
In the Exa-DI project, he co-leads the work on software packaging, deployment, and CI/CD, and in the Exa-Soft project,
he takes part in the work on GPU programming models.
Yushan Wang has been a permanent research engineer at Maison de la Simulation, CEA Saclay, since 2021.
She earned her Ph.D. in Computer Science in 2015, specializing in optimization of computational fluid dynamics (CFD)
simulations for heterogeneous computing environments. Before joining Maison de la Simulation, she worked as an engineer
at the Laboratory for Climate and Environmental Sciences (LSCE) from 2016, where she played a key role in developing
an I/O library for climate models, optimizing their computational resource usage for I/O. Soon after joining
Maison de la Simulation, she began contributing to the PDI library, a tool that decouples I/O concerns from
numerical simulations. Her research interests include high-performance computing (HPC) I/O workflows, particularly
in-situ and in-transit data analysis and in-situ data visualization.
