In this contribution we describe the implementation of a radiation module in the open-source, massively parallel, Particle-In-Cell code WarpX. We provide benchmarks of this module on different architectures, including AMD GPUs, NVIDIA GPUs, and various CPUs. We also discuss how large-scale simulations performed with this radiation module can be used to support the experimental investigation of a novel injector concept for a laser-driven electron accelerator.
The WarpX code is a highly-parallel and highly-optimized code, which can run on GPUs and multi-core CPUs. WarpX is used on the world’s largest supercomputers (including Frontier, Fugaku and LUMI), and was awarded the 2022 ACM Gordon Bell Prize. WarpX has recently become a project of the High-Performance Software foundation.
