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...

Lab stands tall on bi-annual list of Top500 supercomputers

Nov. 17, 2020- 
Lawrence Livermore National Laboratory (LLNL) can lay claim to housing four of the world’s 100 most powerful supercomputers, more than any other institution according to the TOP500 List announced Monday during the virtual Supercomputing 2020 conference (SC20). The 125-petaFLOP peak Sierra, the National Nuclear Security Administration’s flagship supercomputer, remained third in the world...
