exascale supercomputer.
DOE, which heads U.S. supercomputing efforts, has said it doesn't expect to build its first
exascale supercomputer until 2023 at the earliest, a target that has already slipped several years.
Funded by the National Nuclear Security Administration's (NNSA) Advanced Simulation and Computing (ASC) program, El Capitan will be NNSA's first
exascale supercomputer, capable of at least a quintillion calculations per second, about 50 to 100 times greater performance than the current fastest U.S. supercomputers.
