PIConGPU - A scalable particle-in-cell algorithm for graphic cards

We present the main features of PIConGPU, the - to our knowledge - first scalable particle-in-cell (PIC) code for relativistic laser plasma interactions written for graphical processing units (GPUs). We show that it is possible to use PIConGPU on standard compute clusters equipped with GPUs and introduce the main features that are important to reach good weak scaling when increasing both the size of the system simulated and the number of GPUs.
