WarpX is an advanced electromagnetic & electrostatic Particle-In-Cell code. It supports many features including Perfectly-Matched Layers (PML), mesh refinement, and the boosted-frame technique.

WarpX is a highly-parallel and highly-optimized code, which can run on GPUs and multi-core CPUs, and includes load balancing capabilities. WarpX scales to the world's largest supercomputers and was awarded the 2022 ACM Gordon Bell Prize.

In order to learn how to install and run the code, please see the online documentation: https://warpx.readthedocs.io
