Lab stands tall on bi-annual list of Top500 supercomputers

November 17, 2020

Sierra was one of six Lawrence Livermore National Laboratory supercomputers to make the latest TOP500 List of the most-powerful supercomputers in the world. Sierra held on to the No. 3 spot, achieving 94.6 petaFLOPs on the High Performance LINPACK (HPL) benchmark. LLNL’s presence was bolstered by the addition of Ruby, a recently announced computing cluster that hit 3.7 petaFLOPs on the HPL, ranking it No. 80 in the world.
