Modeling plasma wakefield accelerators is computationally challenging. Using cost-reducing algorithms like the quasi-static approximation allows for efficient modeling of demanding plasma wakefield accelerator scenarios. In this work, the latest highlights of the performance-portable, 3D quasi-static particle-in-cell (PIC) code HiPACE++ [1] are presented. The code applies modern HPC practices like a performance-portability layer, standard I/O formats, continuous integration, and is open-source (
HiPACE++ demonstrates orders of magnitude speed-up on modern GPU-equipped supercomputers in comparison to its CPU-only predecessor HiPACE. Therefore, HiPACE++ enables fast and accurate modeling of challenging simulation settings, including the proton-beam-driven accelerator AWAKE [2] or certain positron acceleration schemes.
