Watching gold change structure at extreme pressures

In a recent paper, LLNL researchers and collaborators conducted high-pressure experiments with gold.  

The newly discovered phase of water, Ice XXI, only forms from water under strong supercompression. It is the largest and most complex unit of any ice phase discovered so far.

Experiments show how water could form on exoplanets, disrupting current theories

In a recent study, an LLNL postdoctoral researcher demonstrates a novel pathway for producing significant quantities of water on sub-Neptune-sized exoplanets.

Researchers used Lawrence Livermore National Laboratory’s exascale supercomputer El Capitan to perform the largest fluid dynamics simulation ever — surpassing one quadrillion degrees of freedom in a single computational fluid dynamics problem. The team focused the effort on rocket–rocket plume interactions, achieving better than 500 trillion grid points, or 500 quadrillion degrees of freedom, in simulating the turbulent exhaust flow generated by many rocket engines firing simultaneously.

Gordon Bell finalist team pushes scale of rocket simulation on El Capitan

Researchers used LLNL's exascale supercomputer El Capitan to perform the largest fluid dynamics simulation ever.

Lawrence Livermore National Laboratory’s exascale El Capitan retained its ranking as the world’s fastest supercomputer with a verified 1.809 exaFLOPs (quintillion calculations per second) on the Top500 organization's High Performance Linpack benchmark. El Capitan’s smaller sibling system, Tuolumne, repeated at 12th on the list at 208.1 petaFLOPs (quadrillion calculations per second).

El Capitan retains title as world’s fastest supercomputer in latest Top500

LLNL's El Capitan once again claimed the top spot on the Top500 List of the world’s most powerful supercomputers.

ElMerFold researchers produced high-quality 3D structure predictions for more than 41 million proteins — at a scale and speed previously thought impossible — using Lawrence Livermore National Laboratory’s El Capitan, the world’s fastest supercomputer. This image shows predictions across different biomolecular complexes by the preview release of OpenFold3, an open-source reproduction of AlphaFold3.
