The Advanced Technology (AT) systems sited and in use at LLNL were planned, researched, developed, procured, tested, integrated, and deployed for programmatic computing needs of the nation’s Stockpile Stewardship Program. Projects and technologies include strategic planning, performance modeling, benchmarking, and procurement and integration coordination, market research, and the investigation of advanced architectural concepts and hardware (including node interconnects and machine area networks) via prototype development, deployment, and test bed activities. Planned and current systems include:
El Capitan: Deployed in 2024, The Department of Energy (DOE), National Nuclear Security Administration (NNSA) and Lawrence Livermore National Laboratory (LLNL) have partnered with HPE. to build the NNSA’s first exascale supercomputer, “El Capitan.” El Capitan has a peak speed of 2.79 exaflops (2.79^18 floating point operations per second), ~22 times faster on average than the Sierra system.
In addition to El Capitan, several other sibling systems have been deployed at LLNL and Sandia National Labs: Tuolumne (U) and RZAdams at Livermore and El Dorado at Sandia.
Governance Model
The governance model provides a methodology to effectively allocate and schedule AT computing resources among the three National Nuclear Security Administration (NNSA) laboratories for weapons deliverables that merit priority on this class of resource. Download the document here.
