Getting Simulation and Experiment Closer: Understanding Laser Plasma Interactions with PIConGPU and FLYonPIC

PIConGPU is performance portable and scales up to exascale machines (Summit and Frontier). "Matching" the new model demands large parameter space of complex experimental designs to simulations
needs to be understood and further constrained.

In-situ synthetic diagnostics in particle-in-cell simulations (PIConGPU), such as few-cycle shadowgraphy, coherent transition radiation and Liénard-Wiechert far-field radiation facilitate direct and quantitative comparison to experimental data.

FLYonPIC is an novel addition to PIConGPU, an in-situ rate equation solver, modeling time-dependent atomic physics including excited states, without temperature assumptions.
* Quantitative physics tests show encouraging results.
* Runtime tests show that including atomic physics at scale will require post-exascale systems.
