The original purpose of the design was to simulate nuclear explosions, Atom by atom, split by split in order to comply with a mutual agreement with Russia to cease all live fire nuclear testing. But during development, mission creep set in, and soon the direction of the project included a major push to record all electrically generated data in real time. At the time in 1995, we had the capability with standard Cray super computers to take a snapshot of all the data available on the entire internet every 15 minutes.
