A Hybrid Nodal-Staggered Pseudo-Spectral Electromagnetic Particle-In-Cell Method with Finite-Order Centering
Edoardo Zoni, Remi Lehe, Olga Shapoval +5
Electromagnetic particle-in-cell (PIC) codes are widely used to perform computer simulations of a variety of physical systems, including fusion plasmas, astrophysical plasmas, plas…
Porting WarpX to GPU-accelerated platforms
A. Myers, A. Almgren, L. D. Amorim +20
WarpX is a general purpose electromagnetic particle-in-cell code that was originally designed to run on many-core CPU architectures. We describe the strategy followed to allow Warp…
A generalized massively parallel ultra-high order FFT-based Maxwell solver
Haithem Kallala, Jean-Luc Vay, Henri Vincenti
Dispersion-free ultra-high order FFT-based Maxwell solvers have recently proven to be paramount to a large range of applications, including the high-fidelity modeling of high-inten…
Ultrahigh-order Maxwell solver with extreme scalability for electromagnetic PIC simulations of plasmas
Henri Vincenti, Jean-Luc Vay
The advent of massively parallel supercomputers, with their distributed-memory technology using many processing units, has favored the development of highly-scalable local low-orde…
Pseudo-spectral Maxwell solvers for an accurate modeling of Doppler harmonic generation on plasma mirrors with Particle-In-Cell codes
G. Blaclard, H. Vincenti, R. Lehe +1
With the advent of PW class lasers, the very large laser intensities attainable on-target should enable the production of intense high order Doppler harmonics from relativistic las…
An efficient and portable SIMD algorithm for charge/current deposition in Particle-In-Cell codes
H. Vincenti, R. Lehe, R. Sasanka +1
In current computer architectures, data movement (from die to network) is by far the most energy consuming part of an algorithm (10pJ/word on-die to 10,000pJ/word on the network).…
