Los Alamos National Laboratory (LANL) has been using HPC capabilities to enable science and decision support for the US nuclear weapons complex for 61 years. From the use of ENIAC (Electronic Numerical Integrator and Computer) and building MANIAC-1 (Mathematical Analyzer, Numerical Integrator, and Computer or Mathematical Analyzer, Numerator, Integrator, and Computer) designed by Nicholas Metropolis and John von Neumann, to petaflop-class machines installed in 2009, to the present, LANL has been an avid HPC site. LANL has fielded over 120 supercomputers in 61 years. Throughout the eras of computing-with wires and tubes, transistors, serial, vector, data parallel, process parallel, and heterogeneous-LANL continuously strives to provide users with a state-of-the-art I/O and storage infrastructure, which has historically been challenging.
