Nimrod is a character in the Big Finish Productions audio plays Project: Twilight and Project: Lazarus written by Cavan Scott and Mark Wright, which are based on the British science fiction television series Doctor Who. He is an original character and does not appear in the television series, and should not be confused with the character of the same name from the serial Ghost Light (1989). The canonicity of the audio dramas, like other Doctor Who spin-off media, is unclear.
A special purpose computer that played the game of Nim, designed and built by Ferranti and displayed at the Exhibition of Science during the 1951 Festival of Britain. Later, when the Festival ended, the computer was shown in Berlin. It was the first digital computer exclusively designed to play a game, though its true intention was to illustrate the principles of the (then novel) digital computer for the public.
Nimrod is a tool for the parameterisation of serial programs to create and execute embarrassingly parallel programs over a computational grid. Nimrod was one of the first tools to make use of heterogeneous resources in a grid for a single computation. It was also an early example of using a market economy to perform grid scheduling.
