Today the Department of Energy announced that Cray will build the NNSA’s first exascale supercomputer, “El Capitan.” To be hosted at LLNL, El Capitan will have a peak performance of more than 1.5 exaflops and an anticipated delivery in late 2022. El Capitan will be DOE’s third exascale-class supercomputer, following Argonne National Laboratory’s “Aurora” and Oak Ridge National Laboratory’s “Frontier” system. All three DOE exascale supercomputers will be built by Cray utilizing their Shasta architecture, Slingshot interconnect and new software platform.
