Smilei's users community is growing
Scientific production is rich ...
100 peer-reviewed papers have been published using Smilei
10+ PhD theses in France benefited from Smilei
... and focuses on various applications
LPI/FCI : laser-plasma interaction / inertial confinement fusion
UHI : Ultra-high intensity
QED : Quantum electrodynamics (extreme light)
HPC : high-performance computing
Space plasmas & astrophysics

“Le Comité soutient ce projet dans le domaine en pleine expansion de l’interaction laser-
plasma à haute intensité et qui rassemble quatre laboratoires du Plateau de Saclay (LOA,
LAL, LLR, MdlS) désirant approfondir les connaissances sur l’accélération laser-plasma
(ALP) au travers de simulations numériques. Le Comité souligne la nature structurante
de ce projet qui s'inscrit dans un contexte national et international actif, et qui bénéficie
de nombreux soutiens.”

Smilei workshop - Parallelization 13Developments for LWFA
Envelope model in quasi-cylindrical geometry
supporting ionization and PML
AM “Standard” ~ 24 H Wallclock time / cm of propagation
AM “Envelope” ~ 10 min Wallclock time / cm of propagation
Enjoy next talk by F. Massimo !
The objective is to reach real-time simulation of 1 min / cm of propagation.
Smilei workshop - Parallelization 14(A few desired) Perspectives
●
Next Smilei Workshop (2023 Q4)
●
Centre of Excellence PLAXMA proposed at EuroHPC to reinforce
collaborations
●
Task based implementation (Massimo et. al. PASC22)
●
Spectral solvers integration (See talk by I. Andriyash)
●
GPU release (Grand Challenge Adastra at CINES end of 2022 –
Apollon multi PW)
Smilei workshop - Parallelization 15(True) Perspectives
will become what the community makes out of it.
