Welcome to the Kokkos version of the Vector Particle-in-Cell code, VPIC 2.0! VPIC is a 3D3V, fully relativistic, kinetic, performance-first PIC code for solving the coupled Maxwell-Boltzmann system of equations. Utilizing the Kokkos performance-portable framework, VPIC achieves high performance on multiple CPU and GPU architectures.

The primary documentation for VPIC has moved to Sphinx and is hosted on GitHub Pages here, and located in docs/. The documentation is still a work in progress, but hopefully sufficient to get most users started.
