El Capitan, the National Nuclear Security Administration’s first exascale supercomputer, will likely be the world’s most powerful computer when the system is deployed in Fall 2024. But answering some of science’s most challenging questions will go beyond simply having cutting-edge hardware. Discover how the software architecture and storage systems that will drive El Capitan’s performance — from the Tri-Lab Operating System Stack (TOSS) to the innovative “Rabbit” nodes — will help Lawrence Livermore National Laboratory (LLNL) and the NNSA Tri-Labs push the boundaries of computational science. Learn about the role of open-source software in maximizing productivity, flexibility and reproducibility as LLNL scientists unveil what’s “under the hood” of El Capitan and envision its possibilities for scientific exploration.
