Developing scientific code on the world’s fastest computers

June 10, 2021

While our world class supercomputers garner a lot of attention (we have more computers on the top 500 list as of June 2021 than any other institution!), our use of these amazing machines is enabled by the codes developed to model and simulate complex physical phenomena on massively parallel architectures.

Research Uncovers Missing Physics in Explosive Hotspots

March 16, 2021

Molecular dynamics simulations predict that more potential energy is localized in hotspots than their kinetic energy (or temperature) would suggest. Excess potential energy is tied to persistent strained molecular states that are primed for chemical reactions and explain why hotspots react faster than the bulk.

Lab stands tall on bi-annual list of Top500 supercomputers

November 17, 2020

Sierra was one of six Lawrence Livermore National Laboratory supercomputers to make the latest TOP500 List of the most-powerful supercomputers in the world. Sierra held on to the No. 3 spot, achieving 94.6 petaflops on the High Performance LINPACK (HPL) benchmark. LLNL’s presence was bolstered by the addition of Ruby, a recently announced computing cluster that hit 3.7 petaflops on the HPL, ranking it No. 80 in the world.
