PIConGPU This is a relativistic particle-in-cell simulation of laser particle acceleration in an underdense hydrogen plasma. We use our new tiling memory model to speed up particle in cell simulations on gpus. Simulation data: - 4 x 4 GPUs (4xTesla S1070 an 4 nodes) - 1920x6016 cells, cell size m x m, 2 electron and 22 ion per cell (random position in cell) - one iteration simulates s - sliding window (enhanced simulation area) - every 50th iteration dumped as visualization image for this video - simulated iterations Summary: - particles at start = 233 mill. electron 233 mill. ion = makro particles - simulation run 3 h 44 min 28 s = 13468 s (inclusive image duming from 4 nodes to one shared SATA harddisk) - we use a sliding window to enlarge the simulation area therefore we had electron at the end of simulation Legend: - Green = Laser -
