The road to the NNSA’s first exascale-class supercomputer, El Capitan, began several years ago. This enormous undertaking of meticulous planning and strategic collaborations is already bearing fruit in a number of ways. For instance, close coordination with the DOE Exascale Computing Project, Office of Science Advanced Scientific Computing Research program, and the NNSA Advanced Simulation and Computing (ASC) program has paved the way for secure integration of national security applications with a robust, exascale-ready software stack.
Enjoy this multi-part article series about Livermore Computing’s efforts to stand up the NNSA’s first exascale supercomputer. El Capitan will come online in 2024 with the processing power of more than 2 exaflops, or 2 quintillion (1018) calculations per second. The system will be used for predictive modeling and simulation in support of the stockpile stewardship program.
