Science and Technology Highlights

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.

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.

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).
