At SC25, LLNL earned multiple top honors across exascale computing, open-source software and real-world scientific applications, receiving four 2025 HPCwire awards and a Hyperion Research HPC Innovation Excellence Award.

Widely viewed as the highest recognition in HPC, the Gordon Bell Prize recognizes innovations that push the limits of computational performance, scalability and scientific impact on pressing real-world problems.

Researchers used the 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.

El Capitan once again claimed the top spot on the Top500 List of the world’s most powerful supercomputers, announced today at the 2025 International Conference for High Performance Computing, Networking, Storage and Analysis (SC25) conference in St. Louis.

Scientists at LLNL and collaborators at AMD and Columbia University have achieved a milestone in biological computing: completing the largest and fastest protein structure prediction workflow ever run, using the full power of El Capitan.

LLNL is participating in the 37th annual Supercomputing Conference (SC25) in St. Louis on November 16–21, 2025.

Five years strong, the MFEM workshop fosters connection and collaboration among the computational math community.

Building on our leadership in HPC and AI and our long open-source tradition, ElMerFold is a high performance framework for large-scale inference and distillation on LLNL supercomputers with OpenFold-specific optimizations.

From capturing the chaotic spray of molten metal to the turbulence of fluid flows, the exascale machine is revealing worlds that were previously beyond reach, and it’s doing so thanks to the close collaboration of hardware, software and science teams that makes LLNL uniquely equipped to lead in this space.

Scientists at LLNL have helped develop an advanced, real-time tsunami forecasting system—powered by El Capitan, the world’s fastest supercomputer—that could dramatically improve early warning capabilities for coastal communities near earthquake zones.

The award-winning HPC package manager has seen steady growth and community engagement since its open-source release in 2014.

The latest issue of LLNL's magazine explains how the world’s most powerful supercomputer helps scientists safeguard the U.S. nuclear stockpile.

Among the honorees was the Exascale Computing Project leadership team, which successfully delivered the 7-year, $1.8 billion collaboration among six DOE national laboratories.

Hundreds of current and former LLNL employees, government officials, and industry leaders gathered on January 9 to mark a monumental achievement: the dedication of El Capitan, the world’s fastest supercomputer.

The event marked a monumental achievement with the acceptance and deployment of the first exascale computing system built for the NNSA, a historic milestone in national security and scientific computing recognizing the collaborative efforts of government, industry and scientific leaders.

SC24, held recently in Atlanta, was a landmark event, setting new records and demonstrating LLNL's unparalleled contributions to HPC innovation and impact.

On the newest episode of the Big Ideas Lab podcast, listeners will go behind the scenes of LLNL's latest groundbreaking achievement: El Capitan, the world’s most powerful supercomputer.

Verified at 1.742 exaflops (1.742 quintillion calculations per second) on the High Performance Linpack—the standard benchmark used by the Top500 organization to evaluate supercomputing performance—El Capitan is the fastest computing system ever benchmarked.

The NNSA’s exascale milestone is possible only through successful industry partnerships. Hewlett Packard Enterprise staff share their experiences working with LLNL.

LLNL is participating in the 36th annual Supercomputing Conference (SC24) in Atlanta on November 17–22, 2024.
