6.1 HPC at LANL
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 In-
tegrator, 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.
