The Sierra Era

Nov. 19, 2020- 
This three-dimensional simulation of an idealized inertial confinement fusion implosion shows turbulent mixing in a spherical geometry. Livermore’s Sierra supercomputer makes high-fidelity calculations like this routine, yielding crucial insights into physical phenomena.Lawrence Livermore’s high-performance computing (HPC) facilities house some of the fastest supercomputers in the world, including the flagship Sierra machine. Online for more than a year, Sierra primarily runs simulations for the National Nuclear Security Administration’s (NNSA’s) Advanced Simulation and Computing (ASC) Program. Sierra substantially increases the Laboratory’s ability to...
