LLNL researchers recently used El Capitan's “early access” system (EAS) rzVernal to run a MARBL 3D ALE radiation-hydrodynamics simulation that modeled a laser driven high-energy density experiment done at the Omega Laser Facility. The researchers were impressed to discover the code, which was developed for Sierra, ran well on the EAS machine without any additional changes. The model used 80 MI250X GPUs and consists of 600 million quadrature points. Visualization courtesy of Rob Rieben and Tom Stitt/LLNL.

While LLNL is eagerly awaiting the arrival of its first exascale-class supercomputer, El Capitan, physicists and computer scientists running scientific applications on testbeds for the machine are getting a taste of what to expect. “El Capitan has the potential of enabling more than 10x increase in problem throughput,” said Teresa Bailey, associate program director for computation physics in the Weapon Simulation and Computing program. “This will enable 3D ensembles, which will allow LLNL to perform previously unimagined uncertainty quantification and machine learning studies."
