The future of Laser-Plasma-Simulations - A personal view

Simulations of laser plasma interaction face several challenges. The most important one is having predictive capabilities. While qualitative agreement between experiments and simulations is frequently seen, quantitative agreement is scarce. Predictive capability requires defining your simulated system as accurately as possible and using numerical methods that do not alter your results in an unphysical manner. I'll present how these requirements influence your simulation codes and what role next-generation computers play in the game.
