Tera-10 supercomputer. Worker checking components of the CEA's (Commissariat a l'energie atomique et aux energies alternatives) Tera 10 supercomputer. This enormously powerful computer is capable of processing 50,000 billion operations per second. It is able to predict, with an accuracy of 0.5 mm, what will happen in a nuclear weapon during its firing and combustion, a process that takes a millionth of a second. Photographed in Bruyeres-le-Chatel, France.
