Translational Research: Shrink Accelerator Size & Cost

Algorithm Driven Cache Strategy

High Utilization of Threads

C++11 Fans: Alpaka Talk Thursday 9am - R211A  single-source kernels  real performance portability  CUDA-like, pure C++11  explicit, extendable backends

PIConGPU ─ Scales up to 18,432 GPUs

PIConGPU ─ I/O Scaling

Ion Acceleration with Mass-Limited Targets laser E. d'Humières et al., PoP 12 , 062704 (2005)

The Influence of Target Mount Structures

Paul Trap: Levitate the Target Peter Hilz, LMU

Experimental Observables: Detectors short (500fs), high-intensity laser pulse levitating, solid density target

Energy Scaling: Overestimated in 2D3V  quasi-monoenergetic ions  forward: very high charge

Energy Scaling: Reproduced in 3D3V

Beam Pointing levitating, solid density target

Thank you! Thanks to Peter Hilz (experiment), Thomas Kluge (guidance), Zhao Shuan (in-group Multi2D pre-pulse hydro simulations), René Widera (programming, multi-species), Norbert Podhorszki, Jong Choi, Qing Lui, David Pugmire & Scott Klasky (ADIOS), Henrik Schulz (HZDR HPC), the Titan support-team (ORNL HPC) and Michael Bussmann (group leader). An award of computer time was provided by the Innovative and Novel Computational Impact on Theory and Experiment ( INCITE ) program. This research used resources of the Oak Ridge Leadership Computing Facility at the Oak Ridge National Laboratory, which is supported by the Office of Science of the U.S. Department of Energy under Contract No. DE-AC05-00OR22725.
