Record Notes
El Capitan is an exascale supercomputer at Lawrence Livermore National Laboratory for the National Nuclear Security Administration mission. LLNL describes the system as deployed in 2024, and NNSA announced official verification on November 18, 2024.
TOP500 identifies El Capitan as an HPE system using AMD EPYC / MI300A architecture at DOE/NNSA/LLNL, with measured power of 29,684.62 kW. ADCI uses that benchmarked system-power value as the selected public capacity.
LLNL infrastructure reporting also describes 85 MW of computing-floor readiness and 30-35 MW associated with El Capitan's peak or machine-footprint delivery. ADCI preserves those figures as facility and footprint context rather than treating the current unsourced 40 MW public value as selected capacity.
