Sierra or ATS-2 is a supercomputer built for the Lawrence Livermore National Laboratory for use by the National Nuclear Security Administration as the second Advanced Technology System. It is very similar in architecture to the Summit supercomputer built for the Oak Ridge National Laboratory. The Sierra system uses IBM POWER9 CPUs in conjunction with Nvidia Tesla V100 GPUs.[1][3]
The nodes in Sierra are Witherspoon S922LC OpenPOWER servers with two GPUs per CPU, although originally planned as 3 GPUs per CPU. These nodes are connected with EDR InfiniBand, as HDR Infiniband could not be guaranteed at the time the contract was made.[1][4]
