Productivity from day one on supercomputers that leverage new technologies requires significant preparation. An institution that procures a novel system architecture often lacks sufficient institutional knowledge and skills to prepare for it. Thus, t

We present a subgrid model for laser propagation in a subcritical foam. Our model describes the expansion of laser-irradiated foam elements that are below the resolution of the simulation grid and predicts the plasma conditions that result from burni

pF3D Simulations of Laser-Plasma Interactions in National Ignition Facility Experiments

Autor: Abhinav Bhatele, Steven H. Langer, Charles H. Still

Publikováno v: Computing in Science & Engineering. 16:42-50

The laser-plasma interaction code pF3D is used to simulate laser-plasma interactions in National Ignition Facility experiments. This article describes the optimizations performed on pF3D to enable scaling to a million or more processes. The authors b

We have begun to use 350–500 kJ of 1/3-micron laser light from the National Ignition Facility (NIF) laser to create millimeter-scale, bright multi-keV x-ray sources. In the first set of shots we achieved 15%–18% x-ray conversion efficiency into X
