Single Domain Multiple Decompositions for Particle-in-Cell simulations
Julien Derouillat, Arnaud Beck
As a multi-purpose Particle-In-Cell (PIC) code, Smilei gathers many different features in a single software. Combining some of them is challenging. In particular, spectral solvers…

Adaptive SIMD optimizations in particle-in-cell codes with fine-grain particle sorting
Arnaud Beck, Julien Dérouillat, Mathieu Lobet +6
Particle-In-Cell (PIC) codes are broadly applied to the kinetic simulation of plasmas, from laser-matter interaction to astrophysics. Their heavy simulation cost can be mitigated b…
