PIConGPU - A Many GPGPU PIC Code

Open Alpha

Please note that this is an Open Alpha release for developers and power users only.

Users should wait for our Open Beta release!

Introduction

PIConGPU is a fully relativistic, many GPGPU, 3D3V particle-in-cell (PIC) code. The Particle-in-Cell algorithm is a central tool in plasma physics. It describes the dynamics of a plasma by computing the motion of electrons and ions in the plasma based on Maxwell's equations.

PIConGPU implements various numerical schemes to solve the PIC cycle. Its features include:

  • a Yee-lattice like grid structure
  • particle pushers that solve the equation of motion for charged particles, e.g. the Boris- and the Vay-Pusher
  • Maxwell field solvers, e.g. Yee's and Lehe's scheme
  • rigorously charge conserving current deposition schemes, proposed by Villasenor-Buneman and Esirkepov
  • macro-particle form factors ranging from NGP (0th order), CIC (1st), TSC(2nd) to PSQ (3rd)

Besides the central PIC algorithm, we developed a wide range of tools and diagnostics, e.g.:

  • online, far-field radiation diagnostics for coherent and incoherent radiation emitted by charged particles
  • full hdf5 restart and dumping capabilities
  • 2D and 3D live view and diagnostics tools

Todays GPUs reach a performance up to TFLOP/s at considerable lower invest and maintenance cost compared to CPU-based compute architectures of similar performance. The latest high-performance systems (TOP500) are enhanced by accelerator hardware that boost their peak performance up to the multi-PFLOP/s level. With its outstanding performance, PIConGPU is one of the finalists of the 2013s Gordon Bell Prize.

PIConGPU is developed and maintained by the Junior Group Computational Radiation Physics at the Institute for Radiation Physics at HZDR in close collaboration with the Center for Information Services and High Performance Computing (ZIH) of the Technical University Dresden (TUD). We are a member of the Dresden CUDA Center of Excellence that cooperates on a broad range of scientific CUDA applications, workshops and teaching efforts.
