Hewlett Packard Enterprise El Capitan is an exascale supercomputer, hosted at the Lawrence Livermore National Laboratory in Livermore, California, United States, that became operational in 2024. It is based on the Cray EX Shasta architecture. El Capitan displaced Frontier as the world's fastest supercomputer in the 64th edition of the TOP500 (Nov. 2024). El Capitan is the third exascale system deployed by the United States and its primary purpose is to support the stockpile stewardship program of the US National Nuclear Security Administration.
