Offer Description

The person recruited will be involved in the ANR project called MATURATION (https://www.math.univ-toulouse.fr/~narski/MATURATION/ ) based on the use of sparse grids coupled with the Particle-In-Cell (PIC) approach to study plasma physics. The aim will be to port to exascale architectures an initial 3D simulation code developed as part of previous work [1]. This work will initially focus on scaling up (distributed memory), optimizing CPU algorithms (vectorization) and further GPU porting. The exploration of C++ programming models for performance portability, such as Kokkos or StarPU, will form a second part. A comparative study will evaluate the different implementations in terms of both performance and portability. Performance studies will be carried out on various CPU and GPU technologies, using local resources and access to national supercomputers. The person recruited will also be involved in setting up and sharing best practices in software engineering. This work will be carried out in close interaction with the other MATURATION project partners.

- Participate in the Exascale porting of 3D sparse-PIC code, including distributed parallelism, vectorization, and GPU porting.
- Investigate new programming models to achieve performance portability.
- Analyze code performance on various recent CPU and GPU architectures.
- Enhance software engineering practices related to the code.
- Publish the results of the study.
- Hand over the code handling to the supervisory team.

The workplace is the Maison de la Simulation (Gif-sur-Yvette), a joint laboratory between CEA, CNRS, Université Paris-Saclay and Université Versailles Saint-Quentin. It specializes in high-performance computing and numerical simulations in close connection with physical applications, parallel software engineering, programming models, visualization techniques, artificial intelligence, and quantum computing.
