Abstract
This paper offers an approach to high-performance implementation of the Particle-in-Cell (PIC) algorithm for GPU-enabled heterogeneous cluster systems. We present Picador — a tool for three dimensional plasma simulation based on the fully relativistic PIC algorithm aimed at research of high intensity laser-matter interaction. It scales up to at least 2048 CPU cores with 85% strong scaling efficiency and 512 GPUs with 64% weak scaling efficiency, achieving up to 28% of the peak performance on the CPU and 14% on the GPU, respectively.
