The third of three new exa-scale computers set to be purchased and built by Secretary Rick Perry and the Department of Energy.
Robin Goldstone, a solution architect at LLNL, gave an interview at the Red Hat Summit 2019. She suggested el capitan will be 10x the performance of Sierra (which is 125 petaflops, and "so El Capitan's targeted to be 1.2, maybe 1.5 exaFLOPS, or even more. Again, that's peak performance, it doesn't necessarily translate into what our applications can get out of the platform." In concept, we can use this to "push a workload through 10 times faster or we can look at a simulation that's 10 times more resolved" (better detail).
There will be an El Capitan Center of Excellence at LLNL (deployment and production use from 2023 - 2038). It should focus on AI and machine learning, and advancing the goal of intelligent simulation or cognitive computing.
El Capitan (ATS-4) is the successor to Sierra, and will be succeeded by (ATS-6) in 2027-2028 timeframe.

Highlights of the FY 2020 Budget:
LLNL needs more computing capability to achieve and advance its mission. "More computing capability is needed." (Original in bold.)
