The detailed HPC design uses the world’s largest supercomputers and its most complicated simulation tools to help subject-matter experts choose new directions to improve experiments. CogSim then employs artificial intelligence (AI) to couple hundreds of thousands of HPC simulations to the set of past ICF experiments.

Carbonate minerals are formed when carbon dioxide reacts with magnesium and calcium-rich rocks. But where does that CO2 come from? If it comes from the atmosphere, this process at sufficient scale may be able to reliably draw down atmospheric greenhouse gas levels, according to new research by LLNL scientists.
