In fourth place is the IBM Blue Gene/L system installed at DOE's Lawrence Livermore National Laboratory in the US.
The system hit 478.2 teraflops per second and is used to check the safety, security and reliability of the stockpile of US nuclear weapons without the need to carry out underground testing.
The machine, seen here, was recently scaled up to have 106,496 processor nodes from 65,536.

Think back to the 1940s, Colossus at Bletchley Park. Or the 1950s Cambridge Edsac and Manchester Baby. Or the 1960s Ferranti Atlas.
There were giants in those days.
